Hi, I'm powerblo. I was updating my mods on a nice sunny day when something really bad happened. Not really, but I got an error from Buildcraft. It had to do with the api, so I tried disabled it. Even though, the error came back over and over again. I'm playing the Direwolf20 pack and adding more mods for better experience, and this is what happened. If I get the chance, or if anyone can help, I'll upload the log. Please specify which one, the crash reports might not be much help. If anyone can help, please reply ASAP. Thanks!
