Big Problems after joining Onyxia Server for the first time

Hello there,

i wanted to test out Onyxia and i think that loading these "classic assets" caused some bugs to my client.
my professions window f.e. is completely bugged now, i cant see all my recipes as shown in the image below. Also it doesnt show me the reagents needed

any way to remove everything that might has changed due to that single login?

Close the client and open it again.

If that doesn't help, close the client, remove the cache folder, and open it again.

that picture was taken after deleting the cache folder & restart

It takes a bit for the cache to be recreated, you have to wait a while.
