/**
* Some mods use a custom shape cache with a non-thread-safe map. There is no reason why this wouldn't cause crashes
* in vanilla as well if getShape was called on two threads at once. It seems more likely to happen with ModernFix
* installed due to the dynamic blockstate cache generation, so we solve it by making the maps thread-safe.
