Entities problems

[OriginalUsername]

Hey,
I have a stupid little problem which I can't fix because I'm dumb. I got several custom entities for my story. To make sure it works, I placed the files in the 'entities' folder inside my cs folder. I even made sure the paths were correct, but somehow the game won't load the entities. I saved the map to the right folders, the game loads the right files and I deleted the cache file.
I'm at a loss, could someone help me out?
