It sacrifices old skills, when you're learning 4th Class Skills.
Maybe its not deleting some of them, when you learn your skills with admin command?
Yes i know that old skill needed to delete after learning 4th. but if you can see in screenshot there are skills which needed delete immediately, example the first one ( with sword icon,skill which giving you on the first level)
Server placed on the VDS, and many players test it, they are achieved class and learned skills by yourself.
Thank's for reply.
