I have tried every combination with these weapons and cannot duplicate the bug you reported.
Do this:
1. Make a copy of your Save game file and save it in a safe spot.
2. Delete your Star Trek Mod folder (The one you used for this game)
3. Dowload the full Version of the STM 1.9.0.0
DOWNLOAD
4. Install
5. Download the latest Version
1.9.0.9
6. Install
7. Copy over the save game file and start game.
See if that fixes the bug.
Also send me your save game file so that I can see this bug first hand. Thank you.
