Just noticed an issue with your ruleset and don't know if it's intentional or not.
I tried to replay that disastrous terror mission I talked about above. I did better but still got wiped out. I didn't notice earlier, but when I abandoned the mission, I got 22 points for recovered alien artifacts. My sole surviving soldier didn't bring any alien artifacts with him. To test, I restarted the battle and
immediately took off, and noticed I received 38 points for recovered alien artifacts.
Is this some general OXC thing, or due to your ruleset? Doing some checking, I notice your ruleset has "recoverypoints" lines for the various weapons, such as Machine Pistol, Sniper Rifle, etc. So, it seems the game is counting these weapons as recovered and assigning points. Also makes me wonder if you bring alien weapons with you to a battle and then leave with them, if you also get the points for those. It would appear to be so as I would think it would be consistent, so it seems like a general OXC issue. That aside, do you really want "recoverypoints" assigned to XCom weapons?
