Crazy lag when going underground.

Quack

If I am above-ground, the game works normally. However, when I go to underground to a place like Deepcrag Den or Lower Bthanual, I get terrible lag that makes the game unplayable. This has only happened to me in the past hour. The caves that I am in are not heavily populated, so that is not the cause.

Lag is really starting to get anoying

Having the same issue here. Tried to complete Spindleclutch - nothing but horrendous lag. Then I went to try and clear Cryptwatch Fort and had the same issue. Yet everything else seems to load just fine.

Getting massive lag as well in Abagarlas solo dungeon.
