I get graphical glitches at Cherno, Berezino, the Stary Sobor military base, and all airfields. I am fully up to date with 1.7.2.5 and all files are installed correctly.
I've been getting this all day too and I always get told to "wait until the server responds." Well I wait every time and it always goes to the "debug forest" after anywhere from 10 minutes to half an hour.
