[Bug] AI-Overbombardment and Notification-Issue

[Xilmi]

The AI occassionally overbombards Units. I believe it could be related to Units of other Factions, even those who they are at peace with, residing on the same tile. They bomb as much as if they want to destroy their friends unit, not only their foes.

Another very related issue is the multiple reporting of a unit dying by bombardement.
One drone died but since it was bombarded 8 times (despite having only 0.2 HP) there's 8 reports of the drone dying. In addition to the 8 reports of the drone being bombarded.

The drone had killed a red former the turn before and was left with 0.2 strength on the tile where the cursor is located (between Bab and the colonial soldier).

During the turn one of those yellow 6.6 units swarming around there was on the same tile and red (at war with me, at peace with yellow) decided to kill the drone with orbital strike. One would have been enough but it looks like it bombarded until everything was dead on the targetted tile.
