[0.17.9] Nashlax reporting streaming this game & finding bugs

[Nashlax]

Hi there,

Nashlax here. Last I played this game was years ago so I thought it would be a good idea to stream the 0.17 stuff and actually finish the game for once!

I know there are Bugs, and streaming them actually showcases my last moves before I encounter them!
