Bug:

1. When i typed a command : /give LAKSHYACHAUHAN epicfight:skillbook then i got a skill book but with no skill and then when i try to open it, the game crashes.

Suggesstion For Fix this Bug:

1. The Command is: /give <Player Name> epicfight:skillbook, Change the command to this:
   /give <Player Name> epicfight:skillbook_<Skill of the skill book>
   e.g. --> /give LAKSHYACHAUHAN epicfight:skillbook_roll, /give LAKSHYACHAUHAN epicfight:skillbook_berserker
   ETC.

Version:
Latest version of EPIC FIGHT

Type /give YOURNAME epicfight:skill{skill:SKILLNAME}. For example, if you want to get a Skillbook with a berserker skill, You should type /give LAKSHYACHAUHAN epicfight:skillbook{skill:berserker}

Anyway, the crash will be fixed in the next update.

The skill books use NBT data to show you the skill they're meant to give. Imo there shouldn't need to be a fix for this, as the game crashing when trying to retrieve data from NBT that is nonexistent is normal.

yes, this it that error report showed in my pc
