So I really really like the new autobuild feature in Beta 5. However, I'm a little confused on something. I'll use it to constantly upgrade a ship design, and say it finally creates M4s while I'm using M3s. I'll then try to upgrade those M3s to M4s but on the upgrade menu, but nothing appears. Is this a bug? It would be wayyyy cooler if you could easily upgrade old models to new models.
