A full SkyFactory Server WIPE was completed, all players data got a reset except ranks. There are no major server changes except a big update to the SkyBlock plugin, but most changes are fixes. The restricted items list was also updated, and some other things that will get an update soon are the challenges and add some new items to the spawn shop.
This WIPE was needed to restore the server TPS and stability as the last wipe was about more then 6 months ago there were a lot of large islands left behind that were using resources and so performance was lower.
Enjoy no lag SkyFactory!
