After watching clips of runs I’ve noticed that when she does her lightning call out and puts the sign above the person’s head, that sign can disappear if the person goes into a transformation, like Ice Elemental, and even sometimes when coming out of transformation. I’m not sure if it happens with omac trinket, stealth, and other power’s transformations but I wouldn’t be surprised if the same issue can be reproduced elsewhere. As a player this is definitely a top issue as it causes many wipes.
