Scorched Sand bug

[Cry-El]

I've seen a few threads about this already but nobody has a solution to the problem. The bug is the transfer tanks. I am sure that I've destroyed all 7 tanks but the game says I've only destoryed 6. I am unable to finish the camp, (the patch didn't fix the issue). Anyone know what I should do and please, Avalanche Studios, fix this right away!

I have the same problem, but in the Xbox One version. Still no fix
