UPDATE: nevermind, did it myself. If anyone is finding this via google/search or care to know what happened, the updated dll can be found in my lumber or leather mod (link in sig).
The Universal Fermenter (https://ludeon.com/forums/index.php?topic=33398.0) was made back in 2017 by Kubouch. At some point, it became outdated and was taken over by Syrchalis (https://ludeon.com/forums/index.php?topic=43408.0) for their blueberry mod, and this variant of UF circulates around the workshop now-a-days.
I am one mod developer using UF, but I have run into a bug with it. I brought it up with Syrchalis, but was told they are no longer developing for Rimworld at the moment.
The bug in question is this: UF allows a building to show a "full" version of its graphic using a <graphSuffix> node element. For example you could have an empty bucket and a full bucket graphic and it'll switch over when a pawn fills it up. The problem is that if you save the game and reload while a building is in a full state, the graphic reverts back to the empty version again. It's just a cosmetic bug and the full version will show up again next batch the pawns load into it, but a bug is a bug and a graphical one may be confusing to some users.
Anyway I figure it wouldn't hurt to put a call on here and see if C# gurus are willing to take it on. If you'd like to see this bug in action, you can see it on my lumber mod (https://steamcommunity.com/sharedfiles/filedetails/?id=1708709952). I also downloaded a bunch of other workshop mods that used UF to see if they were having the same problem as I was, and it seemed they were, just to rule out if I may have been doing something wrong.
