Thank you for playing!
We've been getting reports about various issues caused by downloading the game manually. It appears there is a problem with itch.io causing the zip download to get corrupted. Can you check how large your game folder is? Is should be around ~14 GB.
Downloading the game through the itch client seems to solve these issues, so you can also try doing that. (You can don't have to use the client post-download if you don't want to).
If that is not the actual problem, you can find the latest game logs in `Documents\My Games\Sea Dogs\Logs`. Can you zip those up and send them to me.
I would also recommend joining the Discord for easier communitation.
