Gather unknown signals from deep, silent space · By
Trying to play the game for the first time. Tried entering into the tutorial (only option). I was met with great confusion when the game plopped me directly in the world with zero guidance and no tutorial. It took me a great while to figure out that it did not put me in the tutorial at all, and instead into one of the other game modes. I would greatly appreciate this bug being fixed, so I could learn how to play the game
Played this new version and my game has crashed upon some "jumpscare event". I processed the signal and was listening to it, then I pressed "save signal" button and weird crap started to happen - everything paused and various colorful lines gradually appeared on my screen like my gpu was dying. And then at last everything turned to black and a "Fatal error" dialog box popped up. At first I thought that this was part of a jumpscare, but then I found out that it produced the Unreal Engine exception callstack:
Fatal error!

The last three calls are repeated until the end, the whole callstack consists of 100 calls.
Edit: this was 0.8.2b 0006 version.
Loaded up my save and it has such a low framerate that it is unplayable. Plenty of computer resources left in task manager. Normally after pausing (and going to a different window and back) or loading the game is like this for only 10-15 seconds, but this time it just won't go away. Disabling shadows solved the problem, but I've never had this problem before on this version. Is this a problem with my save, or something else?
EDIT: This only occurs in/near the base. However, I have never had this problem last long before and I am only using 66% of my total memory, with VotV only using 12%.
