Re: "Saving Chunks" bug
I was having the exact same problem :/ I just realized it's that the old world somehow crashes the launcher. Hence, me asking if it was possible to just update the minecraft.jar but I think it's just the world. Just restart although it may be hard :/ I have been building my butt off to try and recreate my old city.
Re: Common Problems (And their solutions)
IMO, you need more than 2GB of ram to run the new SSP because it runs through the alternative launcher. Is there a possibility in the future for using the old downloader to modify the .minecraft file so it doesn't crash every time i try to play?
EDIT: I just found the files within the .techniclauncher file and I will now continue with messing with them hopefully getting them to fit into the .minecraft file.
EDIT: I can't get it to work T.T I'll just wait for information.
The only extra mod I use with tekkit and technic is the Mob Spawn GUI by Risugami which comes in handy for starting an army... am I right? And nice profile pic, is that Toph?
