"An unexpected disconnection occured" in avoid ele ailments maps

Hello!

Bug reference: 1023039355

I am playing an elementalist ignite bomber with phys as extra scaling and asenaths.
Under normal conditions, the ignites kill most of the enemies and I don't have disconnect issues. My buddy who is playing a similar build but without ignite gets "unexpected disconnection" when pack size goes too high.

I accidentally put in an avoid elemental ailments map, which I can run because only about half of my actual damage is ignite (deliberately designed for risk farming) - however, I am getting "an unexpected disconnection occurred" when popping too many monsters at once with explosion hits I think?

Probably should be fixed somehow, I imagine the servers are just getting very unhappy calculating all the hits.

Thanks!
