The issue occurs because "offset" is not set under specific circumstances in https://github.com/TridentMC/MovingWorld/blob/1.14.3/src/main/java/com/tridevmc/movingworld/common/chunk/assembly/AssembleResult.java.
I would guess that it is because "AssembleResult(ResultType resultCode, ByteBuf buf)" and "toByteBuf(ByteBuf buf)" ignore "offset".
