I just update to build 33.11. And I made a small mod for myself, few months ago. And I activate my mod for some testing. But the menu bar on the main screen disappeared. And I can not log onto the game with my mod activated, after I closed the game window (because I can't find the "exit" button). I found the following codes from the console.txt file. java.lang.NullPointerExceptionat zombie.scripting.objects.ScriptModule.getItem(ScriptModule.java:1164)at zombie.inventory.RecipeManager.Loaded(RecipeManager.java:77)at zombie.scripting.ScriptManager.Load(ScriptManager.java:1748)at zombie.GameWindow.initShared(GameWindow.java:197)at zombie.GameWindow.init(GameWindow.java:1656)at zombie.GameWindow.maina(GameWindow.java:970)at zombie.gameStates.MainScreenState.main(MainScreenState.java:171) Can any one give me some hint about the cause for such situation?Please.
