Same for me.

Colesium is broken! It also happened to me, i can offer the PIC like yours. 
Now I can't finish the war, and I can't take my rank so I can't get my reward. I need compensation!

Same here. Got pretty excited when the first one went down so quickly, then realized I there’s. No way to finish the battle

Yup spent 30 minutes on one fight before I hit 37% and every attack was 1 hit point. This is a bit ridiculous!!

Same here. Typically finish in top 30. Now I'm at 90 plus. 

Same problème here!

Same.

Yep.  There are a ton of posts about this already.  But I have not seen any communication form EA on all the issues relating to this rollout (including how they took almost most of our Era upgrade materials).  Radio silence.  Maybe because everyone got fired.
