The game soft-locked some 6 ships after finishing. The animation advances a bit when I hover the figures but it does not advance to the next battle.
Do you remember if it was a battle or other event that was upcoming there? Looks like it might be the same issue as here and this was said to happen after navigation event and picking swinger event.
There is most likely some unexpected unhandled error case happening there crewing/equipping the next "enemy" ship and that is then freezing the game. Haven't been able to repro this myself or find what may be the cause so any extra information you might have would be welcome.
