Paging @Dylan

Are you seeing this only once or is it happening a lot? (Also are you maybe able to provide a savegame with it happening - it could even be a new game with some animals if you see it there aswell)

I am also getting this, permanently on the fly
Reference this https://www.reddit.com/r/RimWorld/comments/ft2mc5/error_keeps_popping_up_and_its_lagging_my_game/
Thats another person, through whom i found that this is because animal gear
My git: https://gist.github.com/c671922a14c32c6a47656530fbd72cc6

So this error occurs even if i dont have any armor in my storage. Setting all animals to an outfitrule only for animals armor doesnt work. Setting them to an outfitrule with no gear in does stop thespamming of the error. I have tamed a Thrumbo, set him to an outfitrule where there is only the bridle checked, still gives me the error, without the THrumbo ever wearing it, while his zone is unrestricted (he even hauls to that stockpile)

Thanks for the info! It is still unclear what other mod or condition causes this since 1.1 (likely something does not like animals beeing involved in a routine for colonists), I was not able to acquire a savegame yet in which it is happening, but I am looking into it, there seem to be too few people affected to just mess with stuff on random to see what prevents it (without beeing able to trigger/test it myself) but I may update the mod soon to try to at least get more information on what is actually happening and check on that royalty thing mentioned in the other comments.

Those two logs actually did help, not in that I could find a common mod, but the opposite, there is none that all logs have that I have collected, so I have gone throught everything again and I may have found something related to the royalty thing that may have caused this. I just updated the mod, please let me know if you are still seeing it.

I dunno if its just me but my big boi trunky boi elephants can wear the flak shtuff when their not meant too, theres no model they just look like a default ele but they have all the bonus's of the flak

It is one of the newer features that all can wear the armor, just some might not have graphics yet so it is invisible.

ah right i just wasn't sure cause the descs havent been updated! cant ever be too sure haha

I've found that some of my animals with missing body parts (and in one case bionics) can't wear shield belts. These animals are the Mature flesh beast and the feralisk from Alpha Animals. I haven't tested this with other animals so I don't know the extent of the bug.

That's a better question for Dylan, the author of the base Animal Gear mod (it's one of the requirements for this mod)

I will have a look at it ^^

the Animals Expanded: Australia Kangaroos can't wear any armor, even when allowed on the Edit.

It says they have missing body parts.

Armor on some of the Dinosauria dinos seems to not influence their armor rating properly. (Gallimimus for example does not get any armor bonus with the simple helmet and plate armor)
