Error while compiling: PrivilegeDeploy.cs(110,65): error CS1061: Type `PrefabAttribute.Library' does not contain a definition for `GetAll' and no extension method `GetAll' of type `PrefabAttribute.Library' could be found. Are you missing an assembly reference?

Yup, occuring for me to.
this line:
foreach (var construction in PrefabAttribute.server.GetAll<Construction>())
that GetAll must no longer exist.  it is setting the list: constructionToIngredients use in the EntitySpawned function to do a refund of materials?  Not 100% certain on that.  Since I do not allow these items on my server at all I just coded it to give no refund, hopefully it is not too messed up.  But at least I got it to compile. ;-)  Looking forward to a real fix from the developer.

Having the same issue. I can't even use the plugin at all
