I have no idea how this happened, and have gotten no response from repeated in-game requests for ideas as to the cause. Did I miss a quest that unlocks the other slots?
I looked through screenshots, and my other characters have all 4 slots avaiable in pre-sear. I cant find anything in Options, other than turning weapon bar on/off, I seem to remember something about making them available(think I had to do it with other char), but its been so long, I forgot. Help please!

Thanks alot! Still dont kno how it happened though, as other chars(when created, had all 4 open after I did 1st one, so maybe it changed in patch. Anyway, thanks again, its been driving me crazy for days.
