Hmm. I'll change the spawn point in the future so they don't load under there. For now, you can prevent that by making the window wider so the sidebar isn't in the way. I'll add the "move" and "reparent" buttons back in for the next version as well so grabbing items isn't required.
Also, items made pre v0.1.9d may be weird when updating since their old rotations and scales were bugged. It should be stable now though, like if you make a new custom item it should be consistent. I did lots of testing, so if you experience something weird I'd appreciate a recording or something so I can figure out what's going wrong.
