Ok, not sure how to make the topic title really engaging, but here goes.
I'm working with a mod of my own design and have FRED (v3.6.10 r5055) set to use the mod with the "-mod" command line parameter. I had worked with the mod and FRED together for a while, even finishing a mission involving capital ships with custom weapons.
Recently, something weird came up- whenever I go to look at the weapons for a capital ship (aka Cruisers and up) the field is blank for all primary weapon turrets. Now, there was a duplicate entry in the weapons table, but that was easy to fix. The weapons still function normally in-mission, and using FRED without the "-mod" parameter restores normal behavior. The problem is not unique to the 3.6.10 or 3.6.11 FRED versions. Presently I'm working off of a netbook, but this odd behavior showed up on my desktop first.
Any insights?
