Lots and lots and lots of people have reported it – so here’s a new BuildCraft release ready to download for SMP players, fixing just one issue:
#321 [SMP] investigate exception
fixed java.lang.NullPointerException at at buildcraft.transport.TileGenericPipe.b_(TileGenericPipe.java:84).
Hoping to increase stability. I’m committed to do frequent small releases as long as we don’t get this playable!
