For a small map that we just started, Saving and Loading takes up to 30seconds, without YAMR save less then 2-3s, it also bloats save file (script.dat is 27MB for YARM only where level.dat is 40MB). Game is heavly modded (0.18.22)
Impact is most noticeable at high size setting
Culprit might be all the data you are saving there, is it really necessary to save all this data for each tile on the map marked with YARM?
