lost fully upgraded armored SUV and want to know more about donations

hi my ingame name is sobwo

i was building my base this morning and a AI walk in to my base he shot me i shot back and he exploded i lost a armor SUV with all 4 upgrades and everything in it.

i know lost of item is part of the game but
1 AI never walk this close to our base before
2 as are close to a AI track thing but that is still more then 600m away.
3 the bomber AI have a red ball on top of there heads this 1 and 3 others i have shot did not

so the lost of my SUV is not just apart of the game a good part of it is because of this bug. so i lost a new SUV and upgrades back i can deal with the lost of items inside.

also do u get anything for donations if so how do that work

There is a random chance that a bomber will not have the red ball.
