[BUG?] A/C squadrons loose target

[invernomuto]

Hi,
I put some Zero squadrons in escort mission from Takao to Clark Field (11 hex range), using drop tanks. During turn resolution, none of my bombers were escorted. Next turn, if you select the Zero squadrons you can see that the target is reverted to "commander discretion".
If you put the mouse cursor over the unit icon BEFORE selecting it, the pop up text says that their target is Clark Field but if you select the unit the target is resetted.
Sounds like a bug to me.
