Can yall fix the disconnect bug please?

There's been zero mention of the issue from GGG...what's going on? Literally every 30 minutes the game completely stops, goes to a freeze state, then transitions into a loading / waiting screen with spinning gears, then mobs are able to move and attack while our character hasn't even recovered yet. Typically this ends in a death...which at level 93 is impossible to out-level. The game is quite unplayable in this state. Can we also optimize the on-ground fire effects in maps that produce extreme stuttering? Thank you.
