Hello. A friend and I manage a server together and we decided to make it tekkit. It's been working out pretty well. Minimal lag, hardly any griefs, 10 players on at the least. Things are going good....except for the Swiftwolf Rending Gale ring.
For whatever reason, none of the members can fly with it. As OP you can. I haven't tried as Admin yet but I assume it works for them.
Also, it seems that one of the members have found that if you use mobius fuel, you can fly, but you can't fly if you use glowstone.
As for the plugin list:
WorldGuard
WorldEdit
Votifier
Vault
Towny
TekkitRestrict - Possible suspect
TekkitCustomizer
Stargate
Showcase
Register
Questionaire
OnTime
NoLagg
LWC
Hawkeye
GAListener
Essentials
----- A few other essentials plugins-----
CoreProtect
ChestShop
CFBanner
BKCommandLib
AutoAnnouncer
Ignore the fact that there are two logging plugins. We are transitioning over to Hawkeye, but I want to make sure that if there are any last minute rollbacks, we don't miss it with what is on CoreProtect.
