The overpowered annoying unfair plane and tank enemy AI in Assault Ground Arcade and possible solutions

Had the “2 waves (six groups of six) come at once” bug this morning again. In the 4-5 BR bracket.
When the server hamster absolutely wants to win that game no matter what. lol

Just played assault ground on Kursk at BR 5.0
We won. Yay!

Once back in garage I noticed NO progress on the module I was researching. WTH???
