I was messing around with miniatures nether portal but I probably found a bug.
I was trying to use them for my crucible and I initially succed to link them to multiple molds. At some point i decided to move the portals but then that was when the problems begin. The chunks where properly loaded at all time , both in nether and overworld.
I removed all the portals but then when I lit the first one again it says it links to another one but there are no portal placed in the nether.
I think you can “easly” replicate this problem.
If i understood correctily you have to do the following:
1)Lit 1 portal in overworld.
2) Place 2 portals in the nether as if you want to relay any kind of signal/items/etc back to overworld. 3)Place a second portal in overworld and lit it. Till here usually everything works fine and I am able to relay any kind of signal.
4)Then place multiple portals next to the firtst one. Here things start to behave funny.
I tried to relay a redstone signal. If you lit multiple portals quickly and put a lamp where the signal came out, you can initially see all the lamps on but then they switch off sequentially ultill onlythe last placed one stays on.
5) At this point remove ALL portal.
6) Place the first one again in the same position. It will now link to the previos portal in the nether even if there are no portals in the nether anymore
7) At this point everything stop working properly.
