Minor issues I've noticed in my current game:
1. When I use the "join" command to add asteroid miners to an existing group of asteroid miners, the total number of mining modules (and associated mineral production rates) is not updated. To correct this, I move the entire TG off the asteroid and then back onto it, and then the values are correct.
2. When I use the "land on mothership" command for a TG with both fighters assigned to that mothership and other non-fighters, the non-fighters are deleted. (Preferred behavior: Either an error/warning message, or have them join the mothership's TG. )
3. When I relieve a commander from an assignment and don't give a new one, that commander will sometimes be released within the next few months. Suspect this is because the "time since last assignment" used for releases is based on the date when the previous assignment began, rather than ended. (Preferred behavior: Either calculate based on the end date of assignment, or else make release of extra officers under player control with a toggle. )
4. I've noticed that TGs that are assigned to "repeat" a set of orders that involve jumping through a Langrange point will only correctly execute the jump on the first cycle. After that, they ignore the Lagrange point and just fly directly to their target.
