While making soil types, i thought that it was really rather annoying that clst, which looks like mud/soil with the right tmp, turns into pste when in contact with watr. Granted, one can use sltw, but what would be nice is if clst with a non-zero tmp2 would not turn to pste when in contact with watr. this would be a very small change, but a handy one.
This is not useful and may break saves. Besides, PSTE is mud.
