Is this JJX? Or just simple JJ?
If it is just simple junk jack 1, sadly, there will be no more updates to the game. Since Junk Jack X is out, yeah.
Try backing up all your files to iFunBox or iFile and reinstalling.

Sounds like a corrupted world, maybe. Try restarting your device. Does hitting the continue button also crash?

if restarting doesnt work try what sollision suggested
