I just got a chance to do my first playthrough of SI 1.1 just now, and noticed a couple problems. In case you're having the same problems:
- If the game crashes on startup with "java.lang.ArrayIndexOutOfBoundsException: 9", then you will need to downgrade Special Mobs from 3.2.0 to 3.1.1
- If, when you start the game, you are constantly dumped to the Tinker's Construct armor inventory screen, then you will need to completely disable "Not Enough Keys."
Keep in mind that the downgrade process described here is a workaround; something to help you get to playing before the fixes find their way into the launcher. If you follow these steps, you shouldn't need to do anything once the fix is pushed through. You probably won't need to follow these steps if you're not having the issues, but in case you're playing SMP with someone who is, the version might become an issue, so it doesn't hurt to do this anyway.
To downgrade, you need to perform two steps:
- Disable the existing mods
- Download the lower-version mods into the appropriate folder.
Disabling the existing mods is quite easy:
- First, in the launcher with Survival Industry selected, click on the button labeled "Edit Mod Pack:"
- Then, when the menu is up, click on the offending mod and click "Disable>>"
Adding a new mod is somewhat more involved, but not too difficult:
- Download the mod from Curse. (Special Mobs)
- At the bottom of the "Edit Mod Pack" window is a button labeled "Open Folder." Click it.
- Drag and drop the downloaded mod(s) into the folder opened by the button.
At this point, you should no longer have any problems launching and starting the game. I apologize for the inconvenience this causes, and we hope to have the issues resolved soon.
