Well. The height cap is still there but when you reach the top it loads the next level. There's still a few things to work out before it's seemless. Still a bug improvement.

Ah. Well I'll have to test it out later. The highest block on my old tower is pretty much right on the cap. So if I built higher, it would not be visible from below that transition? And while in the upper portion, the lower unloads and isn't visible then? Still might be cool for a "phantom tower" sort of thing.

Give me one more night before you jump in. I can set it up to transfer the last bit of the bottom world into the bottom of the top world. Will be seamless that way.

I need to update the OP to reflect all the new stuff, but we're back online again. Skyworlds are currently not working and thus disabled, but I will re-enable them as soon as I can. This is my last effort with this. I've been keeping it afloat, just barely. This is the last effort. If you use it and want to see it up then I'll continue hosting, but if it stays as dead as it has been then I'm going to let it go. Let me know if you need any help with anything.

The server has been taken down permanently due to lack of use. You can download the full backup here: Full Server Backup

The above includes all world files so you can save anything you may have built.
