Can't get dev build 647 to work: http://pastebin.com/n9WETbAS

(haven't tried 644 to 646, build 643 is somewhat working (so I'm playing that now), although my water pumps to tank has some issues, haven't been looking close yet to see what it isn't doing right, don't need it that desperately right now).

Thanks, I did now (& should have done before...) :-)

You tried to update your forge to the latest build?
