High latency spikes ONLY in maps

There is high lag spikes only in maps happening for the last 2-3 days and its unplayable. When I return to my hideout my ping is 8-10ms, but in maps my ping goes from 10 to 200 to 50 to 500 to 20 to 10 to 300... you get the idea. Also tested act areas and towns, no problem there. ONLY MAPS ARE PROBLEM!

I already have only one chance and I cannot afford to lose that to your lag spikes. Please fix your servers.

Main servers I connect to are Frankfurt or Amsterdam.
