Hi there! I'm currently playing Ultima III (Ultima Collection DOS version) and I was wondering where the hell are those poison and gas chest traps. Not that I'd be very happy to see 'em exploding on my thief's face but my party is already past level 15 and I've never seen any; all traps I've found on chests were either acid or bomb.

Maybe a bug like bugged chests on Ultima IV (I think it was the bomb trap the one missing there)?

Thanks for your help.
