- Note: could be because im on linux and not something that can be fixed

Start by reproducing the issue with a vendor nearby while another player restocks it, checking whether the behavior is Linux-specific as noted. No source file or test is named; trace the vendor interaction and restock behavior, and consider the bug done when the menu stays closed after a nearby restock.
