You may have another resource that is also streaming one of the modified ymaps in gg-frisbeegolfstand/stream
Unfortunately, there is no easy fix. You could ensure gg-frisbeegolfstand in your server.cfg to load last, which may fix the issue for frisbeegolf but will cause an issue for the other resource.
You may have to not use gg-frisbeegolfstand at all (remove it from your ensures) and update gg-frisbeegolf/config.lua
Config.UsingMap = false
