nah I dunno how long, mojang/bukkit have crappy timing, 1.4.5 rb breaks tons of plugins I use, and now they put out 1.4.6 forcing me to have to update through that mess they have made.
Urrf I have a 1.4.6 bukkit build, but will be a while seeing what is salvage in plugins to get things working, then a server backup.. maybe tomorrow or today (never know).
