I only just found out about that Wanderer glitch yesterday, I just never tested what happens when you lose it but it is fixed now. But that will be fixed in Patch 1.2 which'll hopefully come out in a few days.
I'm glad you enjoyed it though! Bandage heals 10% of the users HP, I might nerf that to 5-7%.
But you played it on a Steam Deck...? Was it running Windows?
