Ritual on Channel doesn't complete

Joined a Channel T5 and got to the sarcophagus room and some of the statues were killed in the circle of the ritual.

I'm currently sitting here in the middle of the ritual with statues standing in the circle, just standing there like they need activated somehow.

Map is bricked because I can't end it early.

Just got to this map - cannot even start ritual, its doing sounds, but is inactive

Also experienced this on a t15 Channel, exited to login screen to come back but the Ritual does not end so I cannot even do the other rituals.

It looks like it occurred due to overlap with the Stone Statue warrior unit and the ritual, then ritual then fails to 'activate' these warriors which bricks the ritual.

Just encountered same problem. Thankfully, it was just a t13, I was trying to finish a level before getting back to 15s. =X
