The game crashed on exit, and requested that I report it. Kinda wished I looked at that dialog a little more carefully, because I'm unsure if this is a Offworld issue or a Unity issue.
Judging from the logs mentioned by the dialog, looks like it tried to read a null pointer. On the other hand, a different log has allocation failure spew, which should be near-impossible on my system, as it has 16GB, unless if maybe it's talking about graphical memory,

I am unsure how to reproduce, I played at least one multiplayer game, maybe two before it crashed.
