Lost interceptors

[PFCWilliamLHudson]

A serious issue repeatedly spotted: during enemy turn, my air unit flies from my Mathematical Medium base on successful interception mission. At the start on my turn, this unit disappears. Attached are autosaves before and after the event.

It seems, the issue does not occur if intercepting unit has its movement zeroed (by pressing Space when the unit is selected) before the end of turn.

Also from this savegame, it seems I can't replicate the issue where the unit disappears. When using the "automate unit" or "automate air defense" orders nothing seems to happen. The needlejet just stays on the base tile.

On another thought, the issue seems to sometimes happen but it takes at least 2 turns to trigger it. The interceptor flies out of the base to the enemy units south and disappers. This might be related to refueling in some way if the unit is already treated as being in flight when the turn starts. Not sure about that.
