Not blaming the mod for my nonsense, but I can "confirm" adding this mod mid-game seems to break map loading (" map.FinalizeLoading()" ). HugsLog[gist.github.com]

Other than breaking Dub's Bad Hygiene ground water (it even tells you to not continue :), there were errors about pawns but they seemed to work fine anyway. I don't think it caused any other issues. I'm using EPOE-Forked and already had bionics/adv.bionics installed and this is how it looked on a pawn throwing an error image[i.imgur.com].
Again, I installed mid game knowing it would cause problems. Removing the mod (after a save! hah!) allowed DBH to work again. No big deal, imma just use your mod in my next colony ;)

At first sight, everything is fine on a new colony so great job, can't wait play with it.
Cheers and thanks for the mod. (reposted to add a bit more clarity)

@TwistedMinds Hello thank you for your report.
I should have fixed the problem that was causing the errors in the console.
I also added a debug action that should fix the missing parts on all pawns in the game (labelled "Fix all prostheses in the world"), just click it once after loading in and the missing fingers problem should be gone!
Let me know if these features work properly!

Incredible! No more broken map loading and the "Fix all protheses in the world" worked (almost!) as intended. It fixed everything nicely beside parts which were already replaced by Alpha Animal's "mutant" part. No errors in the log to show for it, and it's a very specific case ;) Thank you very much for the quick fix! This is fine[i.imgur.com]

Yeah I'd need to make a patch for Alpha Animals for that part to work properly, will look into it tomorrow. Should be easy enough if it just adds human prostheses, else I'm not too sure how to deal with different body types yet.

I patched mutant arm and leg.

Worked fine in my save where I added MSE2 mid-game and used your debug fix. I had no Mutant Legs to fix, but everything's dandy with my Mutant Arms. I was not expecting you to work on that so quickly, bonus point is I have about 10 bionic arms and 50 bionic fingers laying around now :]
Thank you for making this mod, it fixed one of my major issue with the game.

You are welcome :)

Can some one tell me what the hell this means?

Specifically its breaking RIM hud and is just actually breaking my game its interfering with GWP as well and my colonist's arm is just... gone.

Okay. This mod broke the game with RimHUD installed for me as well. Funnily enough, it was working fine until I decided to add some more minor mods into the ongoing game. That's when RimHUD was gone. It also made some toggles in the bottom right invisible and removed the HD faces from the colonists.
Maybe this will help you identify the problem. After removing this mod from the game, everything returned to normal.

@Garr by chance did you used to use the Mod "Mod Medicine Patch" the version that was removed from the work shop and did not require Pharmacist ?
that mod being removed mid save can cause RimHud to break.
Also is it still broken after the version revert ?

This same error came up about 9 days ago on a different save. Slightly different symptoms, but RimHUD breaking was one of them. I doubt that reverting to "two days ago" version will work.
I will try and report here regardless.

strange as I have yet to see an issue with RimHud and MSE 2 fro ma version less than 8 days old

I tested the reverted version of the mod. It seems to be working fine. At the very least, the errors disappeared.
I included the logs just in case:
https://gist.github.com/a88d0c8485d89d3fce6b4635a1dea12b

the only thing I can suggest at the moment is to try and restructure your list following a load order guide (the one on the RimWorld of Magic Wiki has a good reputation for working most of the time), but changing a list is not very Save Compatible.

I doubt it will resolve the issue we are talking about but it can help at some points.
