Extreme Lag in Lair Maps

As soon as my squads started hitting the larger lairs with the spawneries, any action started taking 7-10 seconds. Moving, tabbing between toons, selecting an action, confirming the actions, all have 7-10 second lags. I have 16 GB of ram that shows 25% used in task manager. As soon as I leave the lair map the game goes back to normal.

Don’t want to have to start /winning lair maps because it takes 5 min to do one char with all the lagging.
