The "summoning" ability of drifters given in this mod quickly proved to be too strong on a multiplayer server.  Releasing this update to balance that out and to fix an error.

Tweak:

• Added a min/max duration as well as a min/max cooldown to the ai task that summons other drifters when activated.  This along with the chance for the execution of the ai task to fail seems to give a much better pace to combat.  Having a number of injured drifters chasing you around will still likely result in a mob of drifters coming after you, but it will take quite a bit longer for that scenario to develop.
• Reduced group spawn size of tainted drifters from 2-3 to 1-2.
• Tainted drifters summon only one other drifter at a time rather than 2.

Fixed:

• Nightmare drifters were accidentally set to spawn from the mantle to surface.  That has been corrected. Nightmare drifters now only spawn underground within the same limits as deep drifters.
