[LVL ED] help With Custom stuff

[heyitsrobert97]

Hi, The Level Editor Is Really bugging me. i added a heap of custom items and billboards and planes to my cs and they all show up in game but every time i open the map with level editor it says an error has occured check log. then all the custom items aren't there so i have to redo 30 custom items and rename them and position them right just to fix a small problem. so it takes me 30minutes rather than 30 seconds. does anyone know how to make the editor remember where the items are. any help is appreciated +Rep

I even Changed the file for the billboards so it says File=Four Doors/Mat/Credit.jpg
