Also not showing those nodes, which appears is due to them being empty (in stock*, anyway).
I removed the three ETT (remove empty tech tree nodes) files from the folder and they show up again, but just don't really do anything besides allow you to get the next nodes since they offer no parts. This is fine for me for now while we wait for an update.
Loving this mod, btw!
*not completely stock, I have this mod, MJ, and Extraplanetary Launchpads (without KIS/KAS/whatever that recommended but optional mod for it is) installed
