ultracraft rendering crash fix
The author built this one for Minecraft 1.20.1 on Forge. On other versions it may install and then do nothing.
this mod fixes a crash with connector that made ultracraft crash if you had installed both chloride and oculus upon entering the world
this mod is a very quick fix that literally is just editing the refmap and mixins file
this fix was made by nuhayuponosik so credit goes to him for making it while i was doing irl stuff
also if you are on fabric please support Absolutelyaya who made the actual mod so all credit goes to them and instead download this: https://www.curseforge.com/minecraft/mc-mods/absolute-ultracraft
