I was creating a mission in the new OGL version of FRED... the one with the feature that catches errors in the table files, and it found one in the Amun. It says that there is a discrepancy between the model & the table file where the number & type subsystems is concerned. It says that there are either extra or missing subsystems in either the pof or the table entry, and that a subsystem may need to be added or removed to one of the two. I looked up the model in modview and compared it to the table file and didn't see anything wierd. It might be worth a look. FYI, I was using 2.2c.
Later!
