Description

Attempted to start a battle. Triggers an NPE in Megamek (yes I know this is MekHQ and not MegaMek, but the issue seems to be MekHQ related, and the NPE popup said to post it here). Log and save file attached.

I used GM mode to remove my only aero unit, (and added some others to friendly reinforcements for good measure). The mission launches fine now.

Working fine under the latest nightly, closing.
