I watched the def files, saw 2 hidden unique units, but no hidden angels. Asm already knows about the unique units. Regarding the angels, I'm a bit skeptical, please tell me the names of the def files.
I reviewed my def files and the ZBJECTS source file again - I have 2 def files (AVG2ANG0.DEF and AVGANGLO.DEF), but there is no entry for AVG2ANG0.DEF in the ZBJECTS file, so Wicc is right, or maybe it's just a slightly non-standard setup for me.
