[1.0.5] Durance's fiery staff leaving a static mark on the map

Whenever I open the map when my team is moving, Durance's fiery staff leaves a tiny orange-red static mark on the map in a place he was when the map was opened.

Attached is a zommed map part where you (hopefully!) can clearly see the mark.

I guess this affects not only Durance's staff but also all inventory items that use any kind of particle effect.
