I have submitted a bug report in game but still want to highlight the bug in case it blocks the progression of other CM groups like mine. The bug happens as soon as the third lamp is broken, Qadim would ignore the kiter and Zommoros and go ham on destroying all the platform. See example:
It happened several times in a row to our confusion, thinking something went wrong before confirmed by the internet. Reset the instance wasn't really the option as none of us has the instance; we bought it for Qadim CM, unless there is really no other quick fix way. Here's hoping this bug gets some attention and fix.
