I am using the latest build and I am seeing ATC center (only) give me a freq say 133.4 and as I am changing it I get another one say 128.1   I do respond when ATC ask me to change and that always works with no message back from ATC.  This started happening in he latest build.  2.6.3 beta 3

I get this too, but I keep getting bounced between the same few controllers. 

Nothing has changed that would affect this.

Center controllers are assigned based on the center boundaries and frequencies on the ARTCC tab in TaxiMnt.

There are some routes that cut across multiple boundaries, multiple times, and cause it to seem like you are being switched back and forth.
