After like years playing this, and I logged close to 80 hours previously before these patches, right now I have no clue how to build anything. Also, my base is gone and I can't go back from the station teleporter.

So my really dumb question is how do I build a signal booster or how do I refine chromatic metal? Do I refine it at a base? I saw an image I supposedly have some refinery with me? Why don't I have one or any option to make one?
Also I speak all languages (I did) to nearly perfect but now my character doesn't understand anything?
Can someone tell me what's going on?

So far with the patch, I have already played like 10hrs and it just hit me, that chromatic metal is not found naturally and i don't have a base or refiner and every base I visited according to the salemen I own all blueprints and I can't really make anything. My ship was full of useless tech (according to the game), now my ship is bare and I also got myself stuck in a system with no space station and I'm out of hyperdrive fuel?

I even googled the keys to see if I'm gone crazy:
Move Forward - W
Move Backward - S
Strafe Left - A
Strafe Right - D
Fire Weapon - Mouse 1
Fire Secondary Weapon - Mouse 2
Change Secondary Weapon - Mouse 3
Reload - R
Change Weapon Mode - G
Quick Menu - X
Jump / Jetpack - Space
Swim Up - Space
Swim Down - Q
Interact - E
Melee - Q
Scan - C
Activate Torch - T
Activate Zoom Mode - F
Increase Zoom - Mouse 2
Show HUD - H
Player_Deconstruct - Mouse 3

I don't see a key for build options. So call me dumb or whatever, I can't build anything, I can't even refine chromatic metal or make signal boosters or whatever.

Use the Z key to access the build menu for the refiner, base computer, signal booster etc.. The tool tips bottom right tell also.

I'm guessing that you're starting out in NEXT with an old save. I'd recommend starting over fresh with NEXT since there have been significant changes -- as evidenced by the missing base. The game's early missions/quests provide a gentle way of leading you to learn the bits and pieces of survival and crafting. You don't have to start over but you may enjoy the experience. As davebram noted, there's a "build" key which accesses not only crafting equipment like the signal booster but also building materials, exocraft, and farming. There's a small, portable refiner which you can pick up and carry with you. Copper is what you'll probably start out using to refine chromatic metal.

There's a comprehensive list of refinery recipes over here. You'll get the medium and large refineries, with two and three inputs respectively, as part of the new base quest. The vocabularies of each race have enlarged considerably. When they reworked the language, it's possible that the older translations didn't map over. There is a way to get back at least some of your previous investment. See the discussion over here. The default is Z, as davebram noted. However, I strongly recommend remapping at least some keys. WASD is pure evil (personal opinion ;-).

The real problem is that the default key bindings put the cancel button on Mouse 2 (as in previous versions) but also bind the Secondary Weapon to Mouse 2. So, cancel out of a menu with an accidental extra click and you drop a plasma grenade at your feet. Bad Things Happen. I put the secondary fire back on the middle mouse button (Mouse 3), moved the Change Secondary function to Z, build to G, and Change Mode to Left Ctrl. Move Pickup Item (Player_Deconstruct) to T so it's not shared with the new Secondary FIre and Torch/Flashlight way over to L, since it's not used as much.

Of course, use whatever keybinding makes you comfortable. Just be aware that there have been a lot of accidental deaths with Secondary Fire on Mouse 2.

And I'd really recommend a fresh start. Keep your old save and give it a go in a new save slot, at least.

Thanks for the replies. So ok, I'm just gonna restart this game, too much changes done, there are a lot of things I gotta re-learn and un-learn.
