Weird kinda compatibility issue to report with PrimalCore. Mud blocks act strangely when categorized as granular for the purposes of imposing physics. When they fall onto another mud block they break 100% of the time rather than stack or pile up. Movement over mud slopes is also kinda weird - You sort of slip back occasionally which I thought was cool and intentional at first but there's also an issue where if you fall in a little 1x1x1 water puddle surrounded by mud it's impossible to jump out.
Also I wanted to make all grass-type blocks non-physics enabled so my world stops lagging to heck and generating full of "holes" but still have physics enabled for dirt. Problem is podzol is a variant of dirt so all my Taiga biomes are still laggy and full of holes. Any way to specify block variants in the config?
