Thanks for the report. It didn't happen to our playtesters.
Can you elaborate on how and where did it happen?
For reseting the game, one way is to shift-delete all the game files and re-extract it again.
Yeah so I entered the blackjack and left it after getting the 500 back. After going back in, it gave me the option to play with chips up to a million even though I didn't have it. so I picked the 1 mil curious on what would happen and it put me in -999,500. It compensated for the chips but because I couldn't offer anything, it broke. That's all the info I have on it and i'm sorry I couldn't be of more help. But if you happen to figure out the issue, lmk if it gets fixed!
