updating the server world from atm7 0.2.25 to 0.2.29 doesn't seem to work. transferring the world folder into the new server still causes it to create a new world.

I was unable to replicate this going from 0.2.21 to 0.2.29. Check your server.properties between both server folders and make sure the level type and world name are identical, case sensitive.

I've gone into my server properties for both. both have the same world name but the level type seems to be missing in both the server property files unless I'm looking in the wrong place, sorry I'm still a bit new to this

Yeah the only thing that can be happening is the wrong world name.
