A quick hot fix update for the demo

Howdy!

Thanks to all of those who got their hands on the demo! I've just released a quick patch update that fixes a couple of issues:

• Emails should now work properly in-game (fixes UVN-32)
• USB drives should now not take over your inventory and multiply when you roll back (fixes UVN-33)

If you find any more issues, please do let me know on YouTrack! Thanks again.
