Going back to this stable version, I noticed my new snapshot with better future blocks are visible in the tech loader. You can deploy or swap to them, but of course the new blocks don't load in and any disconnected blocks vanish after the loading animation. I'm thinking it's part of a deliberate change (I think I've asked for this kind of thing, for campaign), but wanted to make sure this behaviour was known. Edit: this is in R&D (and Creative?). Workshop techs with BF also visible.
