#Direct Answer
If you last played before version 1.3.0.1, released September 21, 2026, first check the change that affects the action you intend to repeat: cattle travel, summoning, Magic talents, map markers, Waypoint activation, or early tin gathering. Keep the same task for the first comparison and read the current item and skill descriptions before changing the whole setup.
The official 1.3.0.1 announcement supports the changes below. This is a historical update guide. For later announcements and platform limits, use Version Notes.
#Pick The Old Habit That Matches Your Next Task
| Old habit | Documented 1.3.0.1 change | Useful first comparison |
|---|---|---|
| Cattle are only a source of ranch products | Adult cattle can become mounts with a Saddle or Racing Saddle | Check the saddle interaction and one known travel route before changing the whole pen |
| Minions need repeated expiry-based recasting | Minions persist, with summoning behavior changed | Inspect the equipped tome and cap, then check targeting in one room |
| A remembered Magic talent layout is still exact | Magic talents and mana/barrier rules changed | Read the live talent descriptions and observe a full cast-and-recovery cycle |
| The old small marker set is the whole map interface | Marker icons, colors and hover text expanded | Update the note for one destination you will visit now |
| Waypoints and Portals always need the old activation wait | Activation time was reduced | Read the destination's actual ready state instead of repeating an old timer |
| Tin is as scarce as on an old first-world route | Tin Ore generation in the Clay Caves increased | Search fresh clay; do not assume already explored terrain refilled |
These comparisons help choose a task. They do not prove every later problem was caused by this update.
#Record What You Actually Loaded
Write the installed version, platform, world history and enabled mods before comparing an old guide with your save. A new-generation world and an older explored world are not equivalent samples. An old video's route also may use different generation settings.
Use a backup when investigating a modded save, and follow mod conflict triage for controlled comparisons. In co-op, confirm which host owns the world and that the players are using compatible versions through co-op setup.
#Keep The First Session To One Task
- Name the next action: summon into a known room, travel to one waypoint, mine tin, or recover an old boss attempt.
- Inspect the relevant item, talent or map controls in the installed game.
- Repeat that action from a known starting state.
- Record the first mismatch and any changed input. Do not substitute a different biome or boss halfway through the comparison.
- Continue with the direct guide for that mismatch, rather than opening every update page.
If the save simply has no next milestone, use the returning-player route audit. That is a progression decision, not evidence of a patch bug.
#Choose A Specific Follow-up
| Observation | Next page |
|---|---|
| Marker or return cue is wrong | Map comparison |
| One boss setup fails | Boss preparation comparison |
| Same setup behaves differently across fights | Build comparison |
| Need the changed rule before any comparison | Patch Impact Check |
| Know the ordinary gameplay task already | Guide selectors |
#FAQ
#Is this the latest patch checklist?
It covers the documented changes in 1.3.0.1. Later hotfixes have their own announcements; use Version Notes to match the version you installed.
#Must I restart the world?
This checklist does not establish a need to restart. Separate a changed interface or behavior from world-generation differences before considering a new world.
#Does a review date mean the change happened that day?
No. The article review date is a site-maintenance date. The game change is dated by the official announcement.
#Sources And Review Notes
The official 1.3.0.1 announcement is the source for each historical change in the table. Suggested comparisons and follow-up choices are editorial guidance. This November 10, 2026 consolidation does not claim a new game session, measured activation timer, or universal old-world regeneration behavior.

Returning-save workflow - Sep 21, 2026: Version 1.3 return pass
Added the current patch's highest-risk stale assumptions: cattle and mounts, persistent minions, Magic changes, marker controls, faster portal activation, and increased Tin availability.
Riders of the Underground review - Sep 1, 2026: Return example pass
Added concrete old-save examples so returning players can separate route drift, boss drift, and mod drift more quickly.
Return session examples - Aug 18, 2026: Section update
About, contact, weekly, pages, topic, and policy surfaces now use clearer update language so the site reads like a normally maintained guide library instead of a repeated review template.
Public trust wording was unified across the main navigation and help surfaces - Aug 17, 2026: Section update
Keyword topic pages, footer update labels, and public maintenance wording were tightened so topic landers read more like actively maintained guide surfaces than one-off filler pages.
Topic hubs and trust surfaces were refreshed for the August 17, 2026 maintenance pass

Copy this partUse in game
What to copy from this guide
- Copy the current step, the key action, and the next decision only.
- Use the shortest useful version of the route before adding personal tweaks.
- Stop reading once the answer is clear enough to act on immediately.
Do not copy thisCommon trap
What usually gets copied the wrong way
- Do not treat every side note like a required step for the route to work.
- Do not over-prepare if the guide is meant to answer one narrow issue.
- Do not keep reading wider pages when the exact next action is already obvious.
