Oh wow! I've never gotten that far lol. I'm gonna look into this today so you can get further. Maybe a patch today or tomorrow to fix it.
I'll have a video of my journey up to that point coming out tomorrow (~28 hours from this post) on one of my other channels if it will help, this bug happened after I ended that though, just happened to catch this to see how far I could push it off session. (while improved, the overlapping audio bug is still present too sadly :( - but definitely having fun with the core mechanics so far)
