Maybe another issue with multiplayer and turn sequencing (as the team research is affected by the actions of all players on the team)? Which one was correct?
I think I may have actually seen this in normal BTS also now I think about it. Sadly I didn't take screens or even take note of which one was right.

The starbase bug is quite sad. Luckily, it's only happened to us once, and we are always in permanent alliances vassaling people, so I guess it isn't that much of a big deal.
