Game freezes when aborting Hideout Export

When I'm in my Hideout and abort the export of my HO the game freezes and Windows will recommend to shut it down which is the only option as the game won't catch up anymore. The bug is easy to reproduce.

1. Start the game
2. Login
3. Enter your HO
4. Press "Export"
5. Cancel the export

It is important to know, that the game will NOT freeze when you tried to import a hideout beforehand.
