Had a situation where a PVP battle ended, I clicked “To hangar” on the end of battle screen and upon returning to the hangar was greeted with the popup that the battle was still ongoing and whether I wanted to return to it. As usual, accepting to return to the battle did nothing. My ships were still in battle and no award had arrived.
So I re-logged. Now my ships were out of battle, but the reward for the battle never arrived in the mail, even after waiting several hours for it.
Logs attached.
