Serious error - Content folder's suddenly crashing HPL2

[jssjr90]

Hello, I am relay frustrated of this weird bug that I came cross in the HPL2. I have been developing my mod The Hands Resist Him for about 2 years so far and all of the sudden today, when ever I try to load up a custom content folder of objects and stuff, the HPL2 will crash on me.

I have not touched the folders in months, I did not add or take away content. Everything worked before, but now its like "Sorry you cant use those objects." Which is seriously halting me back from further development. I checked the log file of the HPL2 and I found these common types of errors.

- WARNING: Trying to delete pointer 186964664 in file \Hpl_2\tools\editors\common\EditorThumbnailBuilder.cpp at line 160 that does not exist!

- Cache out of date! Reloading collada file 'C:/Program Files (x86)/Steam/steamapps/common/amnesia the dark descent/entities/A MCS Penumbra/door_air_lock.dae'

ERROR: Bad normal *X number* in mesh C:/ *Folders*

All of these types of errors would very with in the folder that is causing the HPL2 to crash. There are probably hundreds of lines of these types of errors that are present. So can anyone help on this and know how to fix it? I am at a lost.
