I have bad feeling, that count of "zergs" increased in last few weeks, especialy after bug with shorten progess-bars has been introduced. There were time to gather party on every trap before U18 waiting for trapper to disable all traps in the path. Nowadays trappers are incredible fast. This is only one example.
Another example is ED farm in House of Rusty Blades using DD/Fast - Finish/Window.
Please fix this bug ASAP. The game is no longer fun.
