Failure message is "Installation services are only available for purchased upgrades."
Probably related to Black Market is unable to give me my well deserved Weapon or Shield. Note that the problem with the auton bay mentioned in a comment is not fixed in 1.7B2.
I need help reproducing this. I killed the Antarctica and went back to the CSC Terra and it installed the Lamplighter for me.
Looking at the code, I don't see where the problem could be.
Could some mod be interfering?
I'd appreciate any help. Thanks!
I've got a savegame that reproduces the issue. I'll email it to you
@hallmist: Thank you! That did the trick. The problem turned out to be an uninitialized variable, which caused the bug to happen only in Release mode.
The fix will be in the next beta.
