I had pretty much all the techs and i blinked into a block or something and my file is pretty much screwed. I really don't want to have to look for them all again....
If you're stuck inside a block, you should still be able to mine yourself out... starbound doesn't have any concept of suffocation. Your ability to do stuff other than move is not tied to whether or not you can move.
If all of that fails, I'll be adding tech unlocking items tomorrow to my Cheat Equipment mod. So in case you haven't figured it out within a good 8-10 hours, look for that. I'll be heading off to bed now.
I unlock everything for you without you having to mod any files on my server... http://community.playstarbound.com/...ounds-first-modded-server.39794/#post-1421486
