Oshabi fight, stuck due to minion entombment

As the title mentions, the fight does not continue and cycles between the oshabi three damage phases blue, purple, yellow.
Was a Bog map ilv82, no mods only an infused cadiro map device addition, it should not have any bearing however for the full picture may help.
Attached is the proof of image with the bug reference number.
