When I jump on an 101 Expert and trying to send the ZDE datas, the PZB and SIFA circuit just jump off. They doesn't come back when I put them on again. How can I solve that?
Is this for the MFD or analog 101? I had some trouble setting up the MFD last time I tried it, but I chalked that up to forgetfulness since I took a long break from the game.
Never seen this before. However, sometimes you will already encounter failed systems when taking over a loco. Have you tried to reset fault simulation and have you tried with another service? EDIT: and if possible put some screenshots in here. Makes it easier to really understand the problem...
As I have no idea what exactly you are doing I can not help. Unless you post some screenshots and explain the steps you are doing in more detail.
