Really? I don't remember that I gave your game a try so early, if coins are also passively earned, this may explain the 500k+. I'd be glad you give my name to an NPC, to a pet would be great!
Anyway, I restarted from scratch yesterday and reloaded the game/closed its tab a few minutes ago: no bug, no problem, nothing has been lost.
My new save (20251015-1754): https://sharetext.io/e52f0931
Don't bother fixing my old save (and as I previously told you, I don't use Discord at all, this is why I'm using sharetext.io to share my saves) I was still early in game and restarting wasn't much a burden.
Keep the good work! and thanks for having fixed the broken image links ;)
