Oh, odd little bug I just ran into, but it appears if you equip the Sharpshooter Hat onto the Lost Wizard character while she's wearing the Eternal Vow Ring, it will be unequipped once you leave/change the menu, and the "head" slot will temporarily be renamed to a second "weapon" slot. Also, for some reason, I seem to have been given 3 Eternal Vow Rings, not sure if that's intentional or not.
Yes, that's certainly unintentional, haha. I'll be working on a 2.1 version with plenty of bugfixes for later this week, hopefully. Thank you for the report and feel free to visit the game's Discord where we have a full bug reporting channel: https://discord.gg/B5JwPBa
