Are these still causing performance issues? They're relatively chunk efficient and considering people get spot loaders, anyway, that shouldn't be much of an issue, I wouldn't think.
ohh, I thought they are not banned. I added a bypass for the nether, could you please check if it works for you ?
Thanks for looking at it. When I try to place it it in the nether, it gives me an error stating it's banned and only allowed in the nether, so I guess it's not properly detecting it's in the nether.
