The maintenance is over, for the most part. The server has been reopened, gamemode switched back to survival, old worlds, stats, balances and so forth returned. The only two things that are missing are the world spawn, and some Slimefun things.
The world spawn has been deleted and replaced with newly generated chunks, as we suspect the spawn may have some corrupted chunks. We have backed those region files and will do something about it if this indeed turns out to be the case.
Unfortunately some Slimefun data was lost during the maintenance, mainly thanks to the plugin's peculiar way of storing it. This includes most if not all machines, fruits, plants and trees, as well as researches for most players. We will be refunding these things upon request in-game.
Instructions for Slimefun block refunds:
If you find a broken slimefun block, check if it's a head block (skull with a skin) or a regular full block.
If the block is a skull with a skin, you can mine it and pick it up into your inventory.
If the block is a normal block (not a skull), don't break it. Instead make sure to mark down the coordinates.
Preferably register on the discord server and inform a staff about your broken items. Alternatively if a member of staff is online, you can contact them ingame about it. Skulls are relatively easy to refund, and will only take a moment.
If you don't want to register on the discord server and there are no staff online, you can make a post about it on the forums. Forums aren't as frequently checked by staff as the Discord server, so you'll probably have more luck on the Discord server, but we will get to it sooner or later on the Forums as well.
We will probably unlock all slimefun researches for everyone who has been a member before the maintenance.
The server is currently in maintenance debug mode. What does this mean?
It mainly means that the server will be restarted a few times a day, every time adding in more plugins. At present time no plugins are loaded except for essentials. All the old worlds have been saved and backed up, and gameplay is currently taking place in a new world.
Here's some FAQ I'd expect you to have:
Q: Will the worlds be gone forever?
A: Thankfully not. Once all of the plugins have been loaded, we'll add the old worlds back and everything will be back to normal.
Q: What are you doing?
A: Currently we're in the process of making sure the errors we've been experiencing are not on the host side, and if they are, what to do about them.
Q: What can I do now without the world and the plugins?
A: We understand that you probably still want to play. For this reason we've enabled Creative and disabled passwords for everyone until we bring back some plugins.
Q: How long will this take?
A: From 6 hours 2 days, I'd expect.
