Script error while loading map

[Camilla Mondertodge]

I've had this error happen while trying to play a couple of different wads.
Running 3.

Script error, "abort_m_v1.1.1.pk3:gldefs.txt" line 1:
Expected '{' but got identifier 'scene' instead

This most likely means that you are using an old GZDoom version than this mod requires.
