Enemy gold Colossus picks up gold too quickly, causing massive lag

Noticed in Crucible, Fireside:

At later waves, when the gold colossus spawns from gate 2, if its path of destruction takes it near a treasury or piles of gold, it will suck these up and hold them underneath itself, constantly cycling through the pile at its feet -- and seems to collect gold infinitely (i.e., not just for healing), just collecting everything.    This, amazingly, does not crash the game, but slows the frame rate to 1 (CPU limited, looking at other sections of the FOV doesn't provide any advantage unlike graphical lag-causing features).     

If you're playing an aureate monolith method to hoard gold for your Midas doors, this poses a real risk of lagging the game to unplaybility.   

• Specify your platform
  • Window 10 home
  • 64 bit
    • 16 GB RAM
    • i7-6700 4.0 GHz (not overclocked)
    • NVIDIA 1070 FTW (EVGA), latest graphics drivers installed.
• Build: v2.0.8 (not sure of additional build information) 

Recommendation:  Reduce the update speed (add a delay?) of the gold cycling of the collected gold under the enemy colossus' feet, or only permit it to collect enough gold needed to heal / restore shield.
