So I couldn't get steam to run Shogun 2.

So I lookedinto their script.

and found they were running "/config/filename.sh" instead of "config/filename.sh"

Fixing that in the script caused the script to run fine up to the point where it checked if I was running from steam.

So I commented out the steam check.

Then I finally found the errors. It was at this point I decided my clever investigation was done and that I was just putting in a support ticket.

I'm both happy I found out what libraries I was missing and sad that I don't know how to install them.
