huh i started a new game but there are still visual bugs like this
Just to clarify, what operating system do you have?
I know where this issue may come from, but that's why it's necessary for users to make sure BepInEx which comes with a mod is installed and running properly. Which might be an issue on Linux.
Also, just to make a double check - try to put that slave in shower room, wait till it cleans semen sprites out and see if belly goes away. If it does, well... that's an experimental visual feature I had. "Cumflation" where slave's belly increase if "SemenInside" value was maximum. The problem is cloth sprites order which gets screwed just like you see it. Unfortunately, there's little I can do here except cutting/redoing this visual in other way for future releases of the mod. Sorry for that. Currently your best choice to avoid sprite clipping would be to undress slaves.
I just checked scripting data and yeah, 'lower' belly cloth sprite doesn't go away when cum meter is at max (slave's not pregnant). That's my mistake in this version of the mod.
