Upgraded to the 0.3.0 version. When I started a building project, it all went well. Floor got marked, fence went into chest, quick response. When I started placing blocks however, it only treated blocks on the same level as the fence as being in the project. Anything above that level was a "normal" place. It was not replenished in my inventory, and removing it required multiple hits.

Exited server and set defaultHeight in the config file to 50, instead of the default 0. When I reloaded the server and tested again, it had the same result.

Oh dear - I think I messed up the heigh calculations.. As a workaround until I can get the next version released which fixes it, you can build a pillar of fences in the one corner for as high as you need.. that will extend the height of the plan.

Sorry about that..

Building the fence "post" did the trick. Almost everything worked beautifully. Added another issue showing what happened. Excellent work!
