Steam Br 101 Expert "zws" Issue In Free Roam

Upon Loading into a saved Free Roam (on Dresden Leipzig) causes the ZSG to go into an unsolvable fault-state the moment you switch the multitraction switch from 0 to either of the 3.

Communications with the Expert Steuerwagen are from that point forward, impossible.

I have not attempted to check if Sandwich operations would be possible, because i spawned in a fresh 101 and the moment you switch ZWS or BR 120 on it enters fault-state.
