Probably best to wait until Tekkit 3.0 comes out as some mods are going, some are coming in as new, item ids are bound to be changed somewhere, so to save effort and work doing it twice, should probably wait. But on the otherside Tekkit 3.0 could take a while still to come out
AFAIK there is no central bug trackign platform, i think the forums work fine
Also Crafting Table II is extremely bugged and should be disabled on any production server
Did you manually change the block ID to begin with as it shouldnt be changed. Installing a fresh Tekkit should fix it, because if you do change the block ids, each client would have to do the same im pretty sure
First set
check-metadata: true
in modifyworld/config.yml
Then in the permissionsex/permissions.yml
- modifyworld.*
That MUST be below all negative statements, keep it at the very bottom and put all other permissions above it
Are you running version 2.1 of MobCatcher. That's the one compatible with bukkit 1.1-R4 which is what tekkit uses
http://dev.bukkit.org/server-mods/mobcatcher/files/19-mob-catcher2-1/
If you are running that version and errors still persist simply remove the plugin
