Other details

• Originally reported by I.Psychopath#6807 on discord
• Probably there's no way to reproduce this consistently.
• It has to do with image cache, browser side and/or server side, by loading with inspect element on chrome, my cache is disabled and the issue doesn't occur.
• This issue seemingly never happens if server's thumbnail cache doesn't fail.
• You will get this between database deletes, the browser will cache thumbnails for URLs., fro example if http://127.0.0.1:4567/api/v1/manga/1/thumbnail?useCache=true is a cover for manga A and on the second run id 1 is manga B, you will still get thumbnail for manga A, this case is a non-issue and can be circumvented by disabling/clearing cache browser side.

This has happened to me before, when l played around with the C:\Users\your username\AppData\Local\Tachidesk files.
I would recommend deleting the contents of the thumbnails folder.
The app assigns an id to each thumbnail and if two mangas with the same id appear, then it uses the same one for both.

A sure way to fix this would be to just take a copy of that the whole tachidesk folder in appdata, take not of your manga progress and sources and just delete the whole folder and let the app recreate it for you. Then recreate your categories, sources and favorites.

In my view, it would be more advantageous to use universally unique identifiers (UUIDs) for the identification of mangas, thumbnails, and pages, rather than the current numerical IDs. The use of UUIDs would help avoid potential mismatches and facilitate seamless migration between different devices and accounts.

However, it is possible that this consideration is not prioritized in the fundamental design of Tachiyomi.
