The server will update around 2:00PM -6:00 GMT as long as the modpack client side has been updated. This update includes the restoration of nei plugins and the removal of minechem as well as the lotr mod.
Minechem was removed for two reasons, the first being that it's extremely unbalanced, EE3 is more balanced than minechem. You can get 360 iron ingots from 20 obsidian and 24 STACKS of dirt from 12 sand. Secondly, it looks like the mod might be recoded for 1.5
LOTR mod, when a hobbit looks at you the server crashes, so we can't have that. LOTR mod will likely be replaced with another dimension mod in the near future. Factorization will be added next week as well as some new mobs (hopefully).
I actually tried pursuing this route, but after messing around with it, I found out that I can not override recipes that are already there, I can only write NEW recipes. I do really like the idea behind the mod, but until there's a way to configure it so that it's not more overpowered than EE3, I will not have it on the server.
Also, server updated to latest client version.
