During the second reinforcements, I was lagged out of contributing (although I could still get coated in karka babbies with no problem). Then I started teleporting? Then I was completely stuck for a few minutes. Near the end of that portion of the event, I tried to travel the nearest WP in the hopes that it would help with the lag/stuckedness. After ~minute of no response, I suddenly had the transition screen and…that’s it. I ended up logging out and trying to get back in, only to end up in an overflow where the event was already finished.
I received XP/Karma/Silver for the escort portion of the quest, but literally nothing for the part involving the Ancient Karka.
