This has been happening to me as well but only for the Thatch/Fert Silo

my incubator doesnt work, anyone else having this problem?

i think your mod is messing with the beetlses working porperly

Dung beetle ain't "eating" the stacked poop

Suddenly I´m not able to set an egg n poop collector any more. Is this a new bug? Does anyone else have the same problem?

if you cant place structure it is due to an outdated mod causing error in your server config or an error in ark with loading mods. you will need to follow official guide on using steamcmd and gameusersettings to load mods perfectly. try testing in single player see if it works fine alone.

I'm not sure what you mean by dung beetles not eating stacked poop, the poop is remapped to ark poop so its still seen by all others

I've tested the dung beetle, it works perfectly fine for me with this mod. I think the reason is because you didn't know that dung beetles dont actually eat poop, they eat spoiled meat instead. You tame them with poop but after tamed they eat spoiled meat. It also makes oil and fert properly when poop is stuffed in them and no problems with stacked poop, remember they must be set to wandering.
