Savannah Frame skip

I am not sure if this is a bug or performance but I seem to be having issues with frame skips/latency on Savannah maps only, frequently out of all the maps Savannah has always given me trouble when I start a pack I start lagging and my character starts teleporting and if I am lucky I live.

This gets better as more packs manage to die, might have something to do with having an extra Packs modifier to a certain extent filling up the zone.

This only applies to Savannah.
