[15:41:07] [Thread-39/INFO] [STDERR]: [jds.bibliocraft.VersionCheck:getNetVersion:88]: java.io.IOException: Server returned HTTP response code: 403 for URL: http://www.bibliocraftmod.com/vcheck/version.txt

This doesn't seem to be anything to do with buildcraft 👍

In addition this is a standard "403 forbidden" so bibliocraft themselves probably can't do much other than ensure that file is accessible normally?

oh sry i have see buildcraft on the top
