Looks like the same problem but with a sign and chest this time. Honestly, if your crashing cause of pixelmon and mcpc enough to be calling it a "plague" I'd recommend getting rid of one of them untill the issues are resolved.
I guess the issue isn't with Bibcraft - Sorry for the troubles. As for removing pixelmon - it's the whole reason the mods so popular I can't simply remove it, as for a fix - MCPC is remaining quiet on the matter and Pixelmon says its not on their end. So not much I can do
