It is a cross mod interaction that causes the issue, not his machine. His machine merely points out that the issue exists, much like KingLemming's Forge Lexicon. Is it a flaw of the Lexicon that it enables people to convert basic Dyes into Buckets + Dyes? Nope. It just points out a limitation of the Forge Ore Dictionary. It is the job of the server admin to make sure that said conversions are blacklisted in the Lexicon, just as it is the admin's responsibility to ensure the Centrifuge cannot be used to dupe Copper and Tin. Greg was nice enough to make that change mind-numbingly simple for server admins to implement.Ooooor, GT could check which bronze recipe(IC2 or Forestry) is active, and alter the centrifuge intake/output to account for such. I mean, it is his machine that causes the issues after all.
