The slayer creation bug is long fixed. But before unpacking the patch you will need to delete current "ui" folder. Open Data folder properties and untick "hidden" and apply for all files & folders.
Some of you might even enable hidden files & folders, from folder options in windows control panel.
Head/skull prices should be fixed now, if not then please let me know.
Some item tables in DB are kinda messed up, and need to enter prices one by one, so that might take time and will be fixed when bigger and more serious bugs are out of the way.
I will look into the Ouster info tab issue.
Thank you for letting us know, we really appriciate it!
