In the scenario where you have to help pull a train which you couple to in Fulda, the LZB does some funky things. After using the LZB driving to Fulda, coupling, switching to the other cab and drving off the distance gauge is increasing an resetting to 0 after a few hundred meters, leading to an emergency brake application. Turning it off an on angain doesn't help and neither does turning the LZB and PZB off before arriving in Fulda.
