Guys, few days ago i've found a plugin that exact what my server need. It's called Hi-BattleGround but i can't buy it, so i'm looking every where on internet for it because it's a inportant part of my server but no result. I've found many link download like Hi-BattleGrounds 1.5.0 Beta, 1.6.0 Beta but no work. It's seems too many error. I can't even start an arena. So if anyone have something better, please help me !
