Dwarf merchant breaking with new update

The dwarf blacksmith has an issue where you can’t use him - the menu will pop up and you can select an option to upgrade, but after a few times selecting upgrade or add gems won’t do anything. It’ll just show the initial menu you see when selecting an option to upgrade, so pressing these buttons does essentially nothing until you force close and restart the game. Kind of annoying when I’m on a higher floor and need to add a gem on the fly. Has anyone else encountered this?
