I'm going to side with Gistech here. Try loading the weapon (so CIS) first instead of the tactical droid. It's been a while since I've done cross-team weapons like this, but it seems to me that load order would be important. (load droid and weapons included in lvl, load CIS units and weapons in lvl). Since the weapon is not included in the droid lvl and wasn't loaded into memory yet, it's not included when you spawn as the droid.
Of course there's a good chance I'm wrong
