There is a very consistent visual bug in wing 7 raid, specifically on Qadim The Peerless (last boss)
One of the boss's attack "Force of Havoc" is currently visually bugged, Qadim will will lay down a purple electric road (aoe field) and that road will stay for a while, the problem is that this road will dissappear after a while due to a bug and will still hurt anyone who steps on it. This creates confusion for new people as they don't know what killed them.
I made a video showing the bug in effect, kindly consider fixing it. it is very consistent and happens every single time.
This has been going for a while now, veteran raiders usually know about this bug, however, new raiders occasionally fall victim to that bug.
