I play on switch, and everytime you craft, the in game volume decreases by a large amount. It can be fixed by a full game restart, but you don't wanna have to restart the game after every match :/
u/gstaffEpic , u/M_House_Epic , sorry to quote you, but apparently this might be the reason why the master audio can get so quiet?
Thanks for the tag, u/Frogmin. I'll share this thread with the team so we can investigate this possibility.
