New arena not being created

[Fahim Taghavi]

When I install the newest version on my server everything seems fine at first but when I try to make a new arena this is what it says in the chat: An Internal Error occurred whiled attempting to perform this command It says this in the consol: [22:52:43] [Server thread/ERROR]: nullorg.bukkit.command.CommandException: Unhandled exception executing 'splatarena new' in com.shortcircuit.splatoon.commands.ArenaCommand(splatoonarena)at us.Myles.PWP.FakeSimpleCommandMap.dispatch(FakeSimpleCommandMap.java:99) ~[?:?]at org.bukkit.craftbukkit.v1_8_R3.CraftServer.dispatchCommand(CraftServer.java:641) ~[spigotmc-1.8.8-R0.1.jar:git-Spigot-db6de12-75593ab]at net.minecraft.server.v1_8_R3.PlayerConnection.handleCommand(PlayerConnection.java:1162) [spigotmc-1.8.8-R0.1.jar:git-Spigot-db6de12-75593ab]at net.minecraft.server.v1_8_R3.PlayerConnection.a(PlayerConnection.java:997) [spigotmc-1.8.8-R0.1.jar:git-Spigot-db6de12-75593ab]at net.minecraft.server.v1_8_R3.PacketPlayInChat.a(PacketPlayInChat.java:45) [spigotmc-1.8.8-R0.1.jar:git-Spigot-db6de12-75593ab]at net.minecraft.server.v1_8_R3.PacketPlayInChat.a(PacketPlayInChat.java:1) [spigotmc-1.8.8-R0.1.jar:git-Spigot-db6de12-75593ab]at net.minecraft.server.v1_8_R3.PlayerConnectionUtils$1.run(SourceFile:13) [spigotmc-1.8.8-R0.1.jar:git-Spigot-db6de12-75593ab]at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) [?:1.7.0_80]at java.util.concurrent.FutureTask.run(Unknown Source) [?:1.7.0_80]at net.minecraft.server.v1_8_R3.SystemUtils.a(SourceFile:44) [spigotmc-1.8.8-R0.1.jar:git-Spigot-db6de12-75593ab]at net.minecraft.server.v1_8_R3.MinecraftServer.B(MinecraftServer.java:715) [spigotmc-1.8.8-R0.1.jar:git-Spigot-db6de12-75593ab]at net.minecraft.server.v1_8_R3.DedicatedServer.B(DedicatedServer.java:374) [spigotmc-1.8.8-R0.1.jar:git-Spigot-db6de12-75593ab]at net.minecraft.server.v1_8_R3.MinecraftServer.A(MinecraftServer.java:654) [spigotmc-1.8.8-R0.1.jar:git-Spigot-db6de12-75593ab]at net.minecraft.server.v1_8_R3.MinecraftServer.run(MinecraftServer.java:557) [spigotmc-1.8.8-R0.1.jar:git-Spigot-db6de12-75593ab]at java.lang.Thread.run(Unknown Source) [?:1.7.0_80]Caused by: java.lang.NullPointerExceptionat com.shortcircuit.splatoon.commands.ArenaCommand.createArena(ArenaCommand.java:102) ~[?:?]at com.shortcircuit.splatoon.commands.ArenaCommand.exec(ArenaCommand.java:87) ~[?:?]at com.shortcircuit.utils.bukkit.command.BaseCommand.execute(BaseCommand.java:108) ~[?:?]at us.Myles.PWP.FakeSimpleCommandMap.dispatch(FakeSimpleCommandMap.java:95) ~[?:?]... 14 more
