West-East zones wrong background at times

[replicants]

Sometimes I find that I get the west background with the east waypoints when i'm zones with west and east map parts (happens the other way round too).

Happened in Ant, Ferrott, EL and RV.

Sometimes I also find the waypoints from a previous zone being there in addition to the zone i'm in (most noticably EL and Zek).

Its random and happens enough times in a gaming session to be very annoying. Any idea on how I can fix it?

Cheers
