Ban for playing tier 4 of Coliseum

The ban occurs when you beat Tier 3 of the Coliseum, using Luke, IG, and Yoda & Chewie, when they are level 30 or close to that level. 

I wanted to sat that I've been unbanned. Thank you all for your help and support. 
But this does worry me about the state of the games anti-cheat and the progression of Coliseum. Please CG, we need a formal explanation about this problem and solve it asap. It's not healthy for the game to have it's players scared of getting banned by playing this new gamemode

I was banned too, dont play coliseum manually.

Fix this ASAP

EA_Gunner​ this post isn’t primarily about contesting a ban. Being able to beat Coliseum because you upgraded your characters normally, and then being banned for it, sounds like a bug to me. Yes, appealing the ban was part of it, but multiple people are being banned in the exact same manner, a manner in which it seems they shouldn’t be banned. A lot of people are concerned and would like an explanation. Not trying to make your job difficult in any way, we just want to know what’s going on. We don’t want to be banned because of a bug. Thank you.
