I was doing leg:join forces alongside with my co-op partner happily, until we found out that the third objective was bugged. All town centers were destroyed, cataphracts were killed 30/30, and the giant cataphract boss was also slayed. But it still showed like we did not kill the cataphract boss. After waiting like 5 minutes hoping that it would be go to normal, but no, it did not. Thus, 20 minutes wasted. I hope it will get fixed in the near future. ----> I know having a recording would be better, but my pc is not so good it causes fps drops, so I have a few screenshots showing that all the map is cleared. This experience disencouraged me already to not play this quest again.
