Endless loop against Traya when you have Damage Immunity

So yesterday I threw my Beskar Mando team against Traya for a little extra damage. As expected, they didn't do much, but my Beskar Mando threw Damage Immunity on Kuill before he died. My poor Kuill is very slow (I know he should be fast) and ended up being the last one alive. However, Traya kept stealing TM from him. She couldn't kill him, because of Damage Immunity, but he couldn't take a turn either. It was quite literally an endless loop in which I finally had to force-close my game. I feel like there should be some sort of stipulation for Damage Immunity in raids like "blocks all damage from the first 30 attacks" or something like that so that players might not accidentally find themselves in a situation where they HAVE to force-close their game. Just my thought. Wanted to mention it.
