Yeah something isn't right here. I started with cosmics, no dodgy necks and a gem bag in the inventory. It banked, emptied the bag several times and I think tried to deposit it but maybe misclicked? Left the cosmics alone, grabbed some dodgy necks and withrew 20 lobsters. Pickpocketed until it ran out of space (I have eat for space selected so idk why that happened), banked, and threw everything back into the bank, ONLY WITHDREW LOBSTERS and went back to thieving, all the while clicking the disabled Shadow Veil icon, thinking it had runes.
Let me know what other details I can provide to help debug this.
