Latest KOTAMON Patch
As of the August 31, 2026 review, the latest official gameplay announcement is the August 27 post titled CARD UPGRADES and a ton of bug fixes. It clarifies duplicate-card exchanges, adds clearer upgrade guidance and reports fixes affecting cereal boxes, collection displays, localization and cosplay cases.
For the practical impact, check the Cards Hub, Cereal Boxes guide and Money guide. Read the official August 27 announcement for the developer's original wording. This summary does not invent a version number that the announcement did not publish.
August 27, 2026: Card exchanges and bug fixes
The developer clarified that three duplicate cards of matching quality can be exchanged for a better-quality card, including foil cards. The exchange system already existed at release; this update added a tutorial and clearer interface cues, including a yellow highlight and an upgrade button. It was not the first introduction of the mechanic.
The announcement also reports a fix for cereal boxes disappearing around store purchases or entry/exit. Kotalion can no longer be sold, removing the repeat-sale money loop described in older advice. Other notes address collection displays, localization and cosplay-case behavior.
Guide impact: review duplicate handling in the Cards Hub, the changed purchase behavior in Cereal Boxes, and the outdated farming warning in Money.

August 22, 2026: Camera settings and collection changes
This announcement added an option to disable mouse smoothing and noted adjustable field of view. It also increased the chances of finding cereal boxes, figurines and cosplay cases without publishing numerical drop rates.
For players who have maxed all character attributes, the documented cereal-box purchase price at Jenny's shop became $10,000. The announcement also reported trash-bag fixes, localization changes and additional Supporter Pack wallpapers.
Guide impact: use Cereal Boxes for acquisition requirements and Upgrades for the character-progression connection. The Figurines guide retains the distinction between a collection target and a guaranteed spawn route.

August 21, 2026: Balance, saves and achievements
The first major post-release fix adjusted shop prices and increased card and fragment appearances. The developers reported work on save/load interface crashes and added autosaving when opening a new trash heap, alongside saving on exit.
The announcement explicitly said it could not restore progress already lost to crashes. It also described the demo-to-release reset of money and upgrades as intentional while retaining card collection progress. These are historical patch notes, not a guarantee that every later save issue has been solved.
Some achievement checks were corrected, including the white-card set and the all-upgrades achievement. The patch also allowed a valuable item put in the crusher to be picked up again.
Guide impact: start with the preservation steps in Save Not Working, and compare collection targets in Achievements. Do not delete a save to imitate the demo transition.

August 20, 2026: Full release
The developer announced the full release on Steam. Use Where to Play for the verified store identity, or the Beginner Guide if you are starting a new game.
