There is no other state except 1 and it does not grow at all from there?
So it is.
The cause is max_stacks doesn't get set from the database anymore. And because the PubicHair states never had any json files created they have been reduced to a max stack of 1.
So in this case it's an Eccma done goofed up.
To be fair, the builds have been mighty unstable since 0.8.9.2 and there have been so many buggy changes that it must of gotten overlooked.
Attached is a fix, however, keep in mind it was made with 0.9.0.9, so if there are any issues because of this fix, that will be why.
Extract to the game root and overwrite the files (although only the States.rvdata2 will get the overwrite prompt)
