I was jumping around and I fell into a chiminy and I can't jump out, so I tried to Self Delete and it said 'You can't Self Delete within 30 seconds of being stunned.' How do I get out? And I do not have a grapple.
Wow, that has got to be the worst possible time to get stuck there. Can't be stunned out with broken batons, dynamite doesn't work on people in the chimney, no Self Delete, and no hook. Your best bet it to use an alternate account until the server is fixed.
