crashes and performanceproblems

[yxcv]

Hi, ingame i am yxcvasdf.
Since this worldmapupdate today the game keeps crashing every 20-30 minutes. I use google chrome Version 41.0.2272.101 m. It's also really laggy, espacially at the worldmap, and there the mouseover needs a lot of time wich is annoying when i search for farms and have to wait until i know how far my aim is away.
I didn't recognise these problems after the change of our cities, i already tried a reboot but it didn't get any better after that.
