Who would have the nuts to relaunch a server a third time you ask? hehe
All the mods 6 has been reset and launched on 1.8.8, and if I don't see the people who voted for it playing on it at least once, I will ping them once a day for a week.
Desparingly, Chisel and bits has been removed, if you have a complaint, go lynch the all the mods team. Preferably by repeatedly pinging the devs and telling them Scarlet says they smell like old beer cheese.
Old world is not immediately available for download, because, I have no idea how to access the database, and boss is out of town. It should be available sometime in november-ish.
Relaunch was mostly caused by the removal of Chiseled and addition of several world gen mods. I believe a couple new recipes involving ATM stars were also added in the process. There's also quite a few quests now, if you're into that, compared to the initial launch. Anyways, go visit the page here for more details, or alternatively, the github which has commit history, which can be found on previously linked page.
