Hi, this may be a separate bug but still sounds related to OP:
Open Arsenal on I&A #2 server (Alpha Repair Specialist).
Remove all equipment, save loadout (as Test).
Cannot load it again afterwards (see attached image).
Since import/export is not permitted on server, I cannot verify content of the loadout, but basically I removed all equipment (including map, compass, radio, etc) before saving it. Oddly enough, the identical Empty loadout saved during a play session some days ago is working just fine, so apparently it was saved without corruption/issues (perhaps from a different role, Alpha Medic I think).
PS: In my situation above, during the bugged play session, ANY loadouts I saved couldn't be loaded regardless of what equipment or no equipment they contained. I tried some Notepad editing/renaming of the loadouts after, hoping it would fix the bug, but this just corrupted/deleted all my local Arsenal loadouts. So players, don't do that.
