I love how Nexon adds a bunch of stuff then my source of infinite mana does this to me >_> :

(This is what I put in a bug ticket.)

After the latest patch currently about 25-30% of the time when I summon my familiar in town or out in the field, it won't summon and then it seems as a result I can't do anything except move and jump.

For example, if I try to summon my familiar without getting hit or attacking(like just standing in town)and it doesn't actually summon (no cage animation) I can't do anything except movement related things like jumping and able to access the menus, so I can't use skills, use basic attacks or anything like that but I can still heal. So, it's basically anything that involves attacking in some way or buffing.
