I've found 2 issues:
Some times the game crash and then display the message that my video driver has stopped. When I try to open it again, the game always crash on the loading screen before the menu and the only way to play it again is restarting my PC. (I have a RX570).
The second problem I believe it's a bug. I just can't build floor. It just doesn't show up in the building menu. (I already get grass planks, what I believe would be enough to learn this recipe...)
Thanks guys for the game...
