Alice: Currently broken and doesn't even start up (infinite loop in the code), so you can't get on. This will unfortunately be the case for at least another week. Unfortunately, the situation is pretty dire and I need a few hours to devote to figuring out the cause. However, it would be admittedly be easier if we did something else...
Vincent: The griefing around spawn was fixed (a bunch of people were accepted the other day). Note that we need to decide what to do about MC 1.8, so please post on that thread.
Sponge: Sponge is the Bukkit-like thing I'm spearheading. It's progressing with the help of a number of other developers, but I personally can't devote much time to it these few weeks (similar to the situation with Alice), so I can't give a precise update on it either.
If you are a recently joined member, unfortunately this is not a great time to join (unless you like playing on Vincent, then you're set).
Please read: To account for people not playing anymore, we have reset all chunk loaders. Please break and replace your quarries and pumps to re-activate them.
In addition, we have adjusted a setting that automatically loads chunks when mods try to lookup a block at a location, which allowed Ender IO pipes to act as chunk loaders. This likely is the reason why some of your bases depleted resources while you were offline.
We are testing, similar to how it worked on previous versions of Alice, only permitting chunk loading via ChickenChunks. This is because ChickenChunks is the only mod that keeps track of who is loading the chunks. With other chunk loaders, they never ever unload chunks, so even if you haven't been on the server for four months, it would still degrade the server's performance for everyone else who is currently playing.
As of writing, ONLY chunks loaded by ChickenChunks will be loaded. We will be adjusting ChickenChunks accordingly.
