The "buildings, categories, tweaks Primitive" mod is actually this one : Buildings Category Tweaks - Camping https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2993070307
It has been updated on the 31st of March to include the "Survival shelter addon" which is actually named "Repair bed and other additions for Deadmano’s Survival Shelter" https://psteamcommunity.yuanyoumao.com/workshop/filedetails/?id=3082785352

You can safely ignore the error for now. I will probably update the collection in a day or two to include that oneif it fits the current collection.

About the Item Integration error, as mentionned in the "Changelog" thread :

"There will be a "missing mod" error because the Item integration patch is looking for the mod "sparring partners" that isn't included with this collection.
You can safely ignore that error."

Maybe I'll add that one too just to avoid errors, not sure yet ^^

thanks
