Broken glitched wtf help lol

So I finally got 4 player coop up done.... On stats it says I done it all all acts ticked on level select thing I got 4 lil people on bottom right hand corner....

But no cheevie... On Xbox or game and no friendly fire unlock....

Any ideas on how to solve?????

Did you do this after you downloaded RAAMs Shadow?

Yeah finished it after I finished 4 player shadow

I'm quite sure I did it all on arcade as well but I know I 4 playered standard as well on a few levels could it be I missed a level on arcade on 4p as it was done on standard and thus all it needs is a quick run on arcade to make sure it was all done on arcade.... Or has raams shadow screwed me outta a cheevie and mutator and a 100% complete.....

Have you tried clearing your cashe and then finishing a random level in 4 player again?

Cleared cache not played a 4p yet thou will try tonight. Thinking might just 4p start at start go till end or cheevie pops

Tried a couple of random levels on 4p nothing popped looks like a mass coop run is in order if it doesn't pop cheevie after that I really don't know what to do

Um just slowly scroll through looking at each and every chapter making sure you did them all, because it someone left in the middle of a chapter it won't count it, but if majority of an act is played in 4 player it will appear that it was done in 4 player when you may have missed a chapter.

Actually you only have to finish the chapter with 4 players. I jumped into a public game on the submarine level right at the end before the cut scene and got it marked.
