BuildCraft 2.2.11 is on the way, including fixes for three annoying bugs:
 loading SMP worlds may not load pipes properly, e.g. port from 2.2.5 to > 2.2.5 is know to remove all the pipes
 a remaining SMP dupe bug with auto-crafting tables
 fuel can get in the input slot of refineries and be stuck there
All three of these issue, plus a couple of minor ones (http://buildcraft.trac.cvsdude.com/buildcraft/query?status=closed&group=resolution&milestone=BuildCraft+2.2.11) are fixed in the development version. BuildCraft 2.x is really converging now, and I would really like to put this on the side and concentrate entirely on the 3.x branch. For that, I’m now looking for all potential blocking issues still remaining there:
- problems that prevent reasonable game-play
I need BuildCraft community help for that. If you know of any problem in the above category, now is the best time ever to make bug report. See http://www.mod-buildcraft.com/documentation/faq/#bug_report to get ideas on how to efficient there. Thanks to you, 2.2.11 might be the final release on the branch!
