With the new update u can check the exact value of ur tech. its easier to manipulate it now. just make sure you include the decimal. dont change it to anything over 10k. I tested 10k and no bugs. but if you go overboard you might crash the game.
Building and Crafting only go up to 10k with survival 5k and farming 7500. It's bad practice to put in values higher than the limit, especially since the game is so early in alpha.
