Quote:(with the custom entitie's and others)
You have all the custom entities back into your Amnesia? You have added any appropriate directories to the resource.cfg file?
Try to reopen your level, then provide us with the LevelEditor.log file. It can be found at (assuming you're on a Windows, since you mentioned the AAMFP Beta)
C:\Users\<Your_Name>\Documents\HPL2\
In the least, this will give us an idea of any errors which pop up - relating to custom entities or problems from a map or level editor perspective.
