java.lang.NoSuchMethodError: net.minecraft.class_3503.method_15195()V

TagContainer.clear() got removed at some point, probably 1.14.3. I'm gonna need to redo the tag stuff to make cotton scripting work on new versions.

In theory I've fixed it. (replaced it with an accessor + idMap.clear()) Not sure if it works tho (it launches in dev/prod, but not sure if I didn't break anything)

#4 should fix it.

How do you reproduce this?

This doesn't happen anymore, since Mojang changed tag stuff again.
