I can't get in to my game because when I'm trying to open my world I see my hot bar and then the game crashes. It crashed the first time when I went on my Archimedes ship mod ship and it was attached to a bridge that was attached to the land. Here's the crash report: java.lang.ArrayIndexOutOfBoundsException: -1 at java.util.ArrayList.fastRemove(-1) at java.util.ArrayList.remove(-1) at net.minecraft.server.management.PlayerInstance.func_73252_b(PlayerInstance.java:70) at net.minecraft.server.management.PlayerManager.func_72695_c(SourceFile:302) at net.minecraft.server.management.ServerConfigurationManager.func_72367_e(ServerConfigurationManager.java:301) at net.minecraft.network.NetServerHandler.func_72515_a(NetServerHandler.java:626) at net.minecraft.network.MemoryConnection.func_74428_b(MemoryConnection.java:99) at net.minecraft.network.NetServerHandler.func_72570_d(NetServerHandler.java:141) at net.minecraft.network.NetworkListenThread.func_71747_b(NetworkListenThread.java:54) at net.minecraft.server.integrated.IntegratedServerListenThread.func_71747_b(IntegratedServerListenThread.java:109) at net.minecraft.server.MinecraftServer.func_71190_q(MinecraftServer.java:691) at net.minecraft.server.MinecraftServer.func_71217_p(MinecraftServer.java:587) at net.minecraft.server.integrated.IntegratedServer.func_71217_p(IntegratedServer.java:129) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:484) at net.minecraft.server.ThreadMinecraftServer.run(SourceFile:583)

Hello there, I want to delete my modpack to reset the version number. My old modpack got imported into beta.technicpack.net. Now I want to recreate it with new mods and same name, but not as the current version as its listened (2.0). Because it seems I can't "downgrade" versions (to 0.1), I want to delete it from the servers completely to clear the name and slug. But I can't find the remove button (on Technic Platform V1 it was pretty easy). Isn't it not implemented yet or is it well hidden?

If I were to remove necro in an already loaded server world, would it corrupt the world? I know that necro has 1 structure, which spawns in the nether, so would removing necro corrupt the overworld, too? what about chests/ storage w/ necro items in it? Another thing is how would the server owner go about removing necromancy? thanks (:
