That's great!! I wondered what you were doing, good stuff as always.
With the gates, yeah, they're pretty screwed up, the main problem is there's like 3 gates close together in the nether and that's mixing it all up, I tried fixing it with the tower portal but it's still not working entirely.
normally when I make gates I go to the nether first, try to get as close as I can to the co-ordinates in the real world (1/8th)
then I can nearly always come out at where I want the gate to be.
But, there's 3 main problems right now, the first is the number of gates in close proximity to each other, the second, and the reason why space's gates aren't working is because where they should come out in the nether, there is lava, so it moves to the next gate in the nether, so that's why.
The third is old mines, caverns, strongholds, there is a LOT of them in the area where we're making gates, so when I make a portal in the nether I end up coming out underground often, which sucks, lol.
I can work on this and try to fix it for you, though, I have a gate to the snow biome nearby that I was using that I can get rid of to try and stop the interference.
If you guys remember in the old server I had like a loop of dirt floating over the lava? that was because so many of the gates needed to be built above lava and when making gates in the real world, everything would screw up when coming out in the nether.
.. I know it's complicated and annoying, haha. I'll try fixing things!
