Basically instead of taking the stipulated 1, 3 or 5 credits when you place a bet, it adds a zero behind. So the game takes 10, 30 and 50 credits accordingly. Probably not a visual glitch as my units seem to be deducted wrongly too.
Steps to Reproduce
Just place a bet and look at the activity log on the bottom right, it’ll say 10, 30 or 50 credits taken.
