A lot of the users of DW20 seem to be getting crashes similar to this with various machines.

Modlist for DW20 1.0.14 : https://feedthebeast.atlassian.net/wiki/display/PML/Direwolf20+%281.6.x%29+1.0.14

I am guessing this is a cross mod error but I am unable to pin down where the problem is.

Seems like a LogisticsPipes crash to me..

Oh good grief. I put this on the wrong bug tracker. My apologies.

Heh, funny.
