Anarchic Frontiers Minecraft Server

So yesterday I decided to veer away from my current projects and work on my second public farm for the server: a falling object duplicator. This duplicator would especially be useful because on here things like dirt and cobble also fall. However i recieved mixed feedback when talking about it. After coming on later last night a few friends expressed approval for it, and even intangir said that he'd be fine with it.
This is the duplicating machine:

To clear the air: no, I am not breaking or doing anything to the portal frame or the portal itself. Lots of people seem to think I am going to break it. I was merely stating I would create some space by pushing the back wall back and the ceiling raised a bit to make space for the machine.

Unfortunately, someone had a knee jerk reaction and encased the portal room with obsidian, and iron doors that could only be accessed by trusted people. We dont actually know who did this but a lot of people seem to have ideas. Among the people locked out are me, vbelac, and even the server owner himself. Not to mention anyone new who decides they want to explore the end. At this time, a lot of players express that the end isnt something that a small group of people can own, and that these restrictions be removed immediately.

Now, because of these mixed feelings about the farm, this thread will be dedicated to the discussion of its existance. I for one believe that not only should a public duplication farm be built at a public end portal (owned by the public btw lololol), but it would be in everyones best interest since, from what ive heard, a current design for sand duplication is broken.
Let me know what you guys think, should we build it? How should we build it?

Just want to point out this is only one of at least 3 end portals so you are by no means locked out of the end yes there was a group decision to incase the room in obsidian when someone told us we have no say rather or not they can dig in that area and it was made last night to make sure when we got on today there would still be an end portal for us to use yes somepeople may not have been added yet its been up less than 24 hours but they wanna make remarks like their gonna kill me for it they can all they want just know im not afraid in anyway now rest assured if your one of the regulars you will be accessed to this portal of course hold your horses if not there are other portals go find them ik their out there we are not holding the only entrance to  end hostage do what we did and find your own

Might I add Jonin graciously went out into the world and found another end portal for Nohaxjustfloor aka Zev, since he stated he could not find any.

So update time: i ran a few extra tests and tried to exploit some other bugs. Either intangir is hella good at bug fixing or the server is not running 1.10, as one of the bugs used in the duplicator glitch is also responsible for gravel and sand halfslab glitches. This however is not the most troubling bug. The most troubling one is about falling objects are actually deleted when moved into another dimension. Im not sure where this quirk is coming from but I'm pretty sure this is not an intended feature. Sure it means you cant set up a clever tnt portal trap but it also means minecarts might be deleted when moving from portal to portal. An application would be minecart chests moving from one place to the next. I believe this is a bug and as such the conversation will be moved to a new thread when i have a deeper understanding of the bug.

I would like to thank jonin for helping me out. I admit when I mess up but despite everything that happened I think you're a good person. I'd also like to thank Bobwasgoat and Usami for also helping me with the project. As of right now the machine is functional and will be left up. The new portal room will also be rennovated for general use sometime this week.
Have a great day

what are you even expecting to happen?

items normally would spawn around .. spawn i think, but the spawn region on the server is huge, they could be scattered anywhere in a 400 block radius

Im sending falling entities from the overworld into the end while simultaneously causing an update to their movement, causing them to double when they appear on the other side. For reasons im still investigating NO falling objects are being sent into the end and I believe it is a bug.
