I experience that as frequent as once or twice a day since the Patch 9.5 has been released, I tested it with different mods too, and it was resulted without any difference, so there are some possibilities, viz:
1. some mods, including Aslain, got the same compatiability problem with the Patch 9.5;
2. Patch 9.5 got BUGS;
3. Java problems in mod as I always got js error message during mod installlation.
Just my guess, please comment..!!!
