Landmarks are intended to be banned in other worlds then the overworld to prevent big quarrys. Unfortunately there is an issue with the permissions which requires the player to relog sometimes.
Thank you all. Are builders from buildcraft banned too? not in banned list, but made one and it disappeared when I placed it with the banneditem notice popping up. Also would it be possible to enable /rt in the nether, or is there a specific reason for this not being possible like the /rt out of boundaries problem?
@SirWill They seem to be disabled on purpose, do you know why and why they are not on the banned item list?
Builders are bugged for a while now and haven't been updated. They cause world corruption and are disabled by default by the pack itself.
Hmm, maybe they did get an update from 1.6 to 1.7 then. I hope they are fixed then (but I wouldn't risk it). They were very reliable though, Once you use one you can 100% rely on them causing your world to die.
When I right click on a monster spawner it tells me "You do not have permission to do this" also tells me that when I pick it up with a diamond dolly, is there some other bug with this?
