The title pretty much says all. Dropped items don't go through nether portals, and my farm design really hinges on that feature... Is this a bug? Or was it programmed to do that on purpose? Any feedback helps... Thanks.
Items going through portals keeps chunks loaded, that would cause a tremendous amount of lag on the server. Furthermore, there is nothing that I have found as a replacement either: There is not a way to keep a chunk loaded (other than you being there) to my knowledge; believe me, I have tried.
There also have been duplication issues involving minecarts and items with portals in the past. I don't know if this is the reason, but that is the only fix I know of for the glitch.
And if you do find a way you'll report it to me so I can fix it Nether portals are constantly a source of duplication issues, as there currently is a dupe exploit involving them... Thankfully it doesn't work on EMC because we disabled that feature of MC.
