The Quickbar disappears when i press ESC to get into the menu where you can exit etc. and when i close said menu the Quickbar doesn't show up again.

I can get the Quickbar back by going into settings then turning the quickbar off, going out of the settings and closing the menu and then going into settings again to turn the quickbar on again.
The Quickbar is now showing but whenever i press ESC again to get into the menu it disappears and doesn't reappear when i close the menu.

This Bug also carries over restarts, when i close the game while the quickbar is not showing it doesnt reappear when i restart it.

The Quickbar is visible in the Inventory but disappears on closing the inventory.

This has happened to me on Official and Community Servers. Game version is stable 1.0.150192.
