This is a simple stack size setter for stone chunks. It's based on "Stackable Chunks [1.4]" ( https://steamcommunity.com/sharedfiles/filedetails/?id=2373632580 ) but does not have a configuration UI. It will set the stack size for all stone chunks to 250.
If you add this mod to an existing save, all chunks on your map will disappear due to the fact that the default def for chunks has the compressible attribute. Newly generated chunks will not be affected.
