Describe your problem, including steps to reproduce it

Don't know, crash started after my modpack was published to curse... didn't happen while i was testing for issues....

Any other comments?

Looks like one of the .json files in your config/pneumaticcraft folder is corrupt.

I've added a change to log an error (including the exact file where the error occurred) and continue if this happens; can you try build 149 from http://jenkins.k-4u.nl/job/PneumaticCraft-Repressurized/ and see what you get? (and paste a copy of the erroring file)

Closing due to lack of response. Issue should be resolved in build 149 (better error logging in case of invalid JSON)
