OH 3 - Z-wave Stick resetting when switching tabs in the controller-thing or excluding devices

No, I made sure of that. The controller is working fine (except for some weird thing-issues that I did not figure out yet: OpenHAB 3 zwave items/channels only updating after saving the item).

Only when clicking on “Exclude” it will reset.
Even clicking on “Synchronize Network” (even though not applicable) will trigger the reset.

I am on the latest snapshot btw: 3.1.0-SNAPSHOT - Build #2109
