Haha, the truth is, in the final testing stage before release I encountered a serious crash caused by one of the more internally complicated new features (one of YOUR requests, to be specific =p), so there was no way I could release last night. I fixed it around 12:30 AM and had to wait until this morning to confirm the fix with more testing, and do all the release-related prep.
(It turns out the process to make sure the game remembers and loads your parts in the same order after map transfer / save loading was somewhat involved...)
