Posted June 29, 201213 yr Whenever I try to generate a world with Minecraft Forge (and 37 other mods! Phew.), I get the following error message after a while: 2012-06-29 20:16:59 [sEVERE] A critical error has occurred. java.lang.NoSuchMethodError: vx.onGUICreateWorldPress()V at xh.a(GuiCreateWorld.java:209) at vp.a(SourceFile:74) at xh.a(GuiCreateWorld.java:316) at vp.f(SourceFile:122) at vp.i(SourceFile:110) at net.minecraft.client.Minecraft.k(Minecraft.java:1567) at net.minecraft.client.Minecraft.x(Minecraft.java:822) at net.minecraft.client.Minecraft.run(Minecraft.java:750) at java.lang.Thread.run(Unknown Source) 2012-06-29 20:16:59 [sEVERE] 37 mods loaded Minecraft Forge 3.3.8.152 FML v2.2.78.153 Forge Mod Loader version 2.2.78.153 for Minecraft 1.2.5 mod_CodeChickenCore : Available (minecraft.jar) mod_MinecraftForge : Available (minecraft.jar) mod_NotEnoughItems : Available (minecraft.jar) mod_ReiMinimap : Available (minecraft.jar) mod_IC2 : Available (industrialcraft-2-client_1.95b.jar) mod_AdvancedMachines : Available (AdvancedMachinesClient v1.5.zip) mod_AdditionalBuildcraftObjects : Available ([email protected]) mod_BuildCraftCore : Available (buildcraft-client-A-core-3.1.5.zip) mod_BuildCraftBuilders : Available (buildcraft-client-B-builders-3.1.5.zip) mod_BuildCraftEnergy : Available (buildcraft-client-B-energy-3.1.5.zip) mod_BuildCraftFactory : Available (buildcraft-client-B-factory-3.1.5.zip) mod_BuildCraftTransport : Available (buildcraft-client-B-transport-3.1.5.zip) mod_BuildCraftSilicon : Available (buildcraft-client-C-silicon-3.1.5.zip) mod_AdditionalPipes : Available (buildcraft-client-DA-additionalpipes-3.1.0.zip) mod_EE : Available (EE2ClientV1.4.6.5.jar) mod_EnderStorage : Available (EnderStorage-Client 1.1.3.zip) mod_Forestry : Available (forestry-client-A-1.4.6.2.jar) mod_BuildCraftZFP : Available (forestry-client-A-1.4.6.2.jar) mod_IC2NuclearControl : Available (IC2NuclearControl_client_v1.1.9b.zip) mod_PigbearLaser : Available (Laser Mod 1.5.zip) mod_CompactSolars : Available (mod_compactsolars-client-2.3.2.10.zip) mod_IronChest : Available (mod_ironchests-client-3.4.2.28.zip) mod_PortalGun : Available (portalgun) mod_Railcraft : Available (Railcraft_Client_5.3.3.zip) mod_RedPowerControl : Available (RedPowerControl-2.0pr5b2.zip) mod_RedPowerCore : Available (RedPowerCore-2.0pr5b2.zip) mod_RedPowerLighting : Available (RedPowerLighting-2.0pr5b2.zip) mod_RedPowerLogic : Available (RedPowerLogic-2.0pr5b2.zip) mod_RedPowerMachine : Available (RedPowerMachine-2.0pr5b2.zip) mod_RedPowerWiring : Available (RedPowerWiring-2.0pr5b2.zip) mod_RedPowerWorld : Available (RedPowerWorld-2.0pr5b2.zip) mod_SneakyPipes : Available (SneakyPipes-0.1.1.zip) Steve's Carts : Available (Steves Carts 1.4.4.zip) mod_WirelessRedstoneCore : Available (WR-CBE Core-Client 1.2.2.1.zip) mod_WirelessRedstoneAddons : Available (WR-CBE Addons-Client 1.2.2.2.zip) mod_WirelessRedstoneRedPower : Available (WR-CBE RedPower-Client 1.2.2.1.zip) mod_ThaumCraft : Available (ThaumCraft2.1.6d.zip) I apologise for not being able to get the error message Minecraft itself gives me (MultiMC really hates error messages!).

I just want to have all the data I can manage.
June 29, 201213 yr Something is either overwriting Forge files in the jar, or Forge was not installed properly is what I would guess from that.
June 29, 201213 yr Author I removed Generator Ports (needs updated to new Forge, methinks!) and made a new level. It worked like a charm. Thanks!
July 1, 201213 yr A mod that installs the old generators for 1.8.1, B1.7.3, Alpha+ Alpha with snow, And Classic And for the error all mods that includes forge patches for the build that forge intergrated modloader with (sorry forgot number) will make a conflict if they edit vx.class even if it includes a patch
July 1, 201213 yr No mod should be overwriting any file that forge touches, if they do then they are instantly unsupported. If they need to make a base edit that cannot be done by other means, no matter how small, then they should supply a pull request for forge. Forge is designed to eradicate base edits so every mod is just drop-in-mod-folder installable. Old generators, like biome generators? Scott is making an api for things like that, but even know you can overwrite the stock generation world instance with reflection so base edits should not be necessary regardless.
