that it, no error log.

confirmed

Take a look at the github home page for the plugin: OtherBlocks (now known as OtherDrops) plugin for Bukkit (dev build: https://www.mediafire.com/?i6ows1g6kus2o0l) http://dev.bukkit.org/server-mods/oth…

try out the dev build; it works fine on 1.9 for me.

EDIT: Ooops, realized I wasn't actually using that version. Use the one updated for 1.9 by yeahwhat-mc
