Hi, the Laser weapon issue is now gone (probably I installed something incorrectly).
I've had three other minor issues, though.
1. On the Barge mission, the Alien turn takes a long time. It seems related to Hallucinoids getting stuck in doors or something like that (after all Hallucinoids are killed, the Alien turn returns to normal). The mission is still playable, it's just that it takes longer than it should.
2. Gas Heavy Cannon - bodies aren't displayed if they're in the same tile as a dropped HGC. I mean on the main screen, not the inventory screen.
3. Sometimes there's a map error reported, though the mission is still playable. Here's the info from the game log:
