You seem to be among the people who've gotten their resource cache polluted with old-client resources. I still have no idea how some people keep having this happen to them. I'm suspecting it's some sort of custom client issue, but I have no real idea.

Many thanks, Loftar. I could realize that this is somehow connected with cache. Removed all HnH folders from appData - now it works
