Just adding that I am getting the same crash in single-player with same Calculator and Sonar Core versions as above. This is in 'Beyond the Skies' mod pack. -- Edit -- I took a look at the code - the error occurs checking to see if an item is blacklisted. I deleted my "AtomicMultiplier-BlackList.cfg" file and let it get re-created on launch, and it works now. Must have been an improperly formatted entry.
