In the Jakku GC it appears I can only apply stealth once from any team member. For example i can only use R2's stealth ability once. All subsequent attempts he just spins around but no one gets stealth. The only debuff I see on my team is the overheat that's applied at the start of battle, but I didn't read anything about it affecting stealth. I've tried other characters ( Shaak Ti). Same results, after the first stealth, subsequent attempts to stealth fail. I must be missing something.
