Pretty much I got LZB zwamsbremsung just outside of Augsburg. It wouldn't free up by using PZB Frei and stuff. LZB freed up when I got out of my seat, pressed override, turned the battery off and on again, raised the pantograph. At this point, LZB was no longer beeping. However, I could not draw power. I tried spamming all the PZB buttons to see if there was some glitch where LZB was still incapacitating me without showing it. But then I went to activate AFB to see if that had any bearing on power draw, and it did, which doesn't make any sense because you should be able to drive it without AFB because AFB is exclusive. So you got some sort of bug here with LZB on the BR 403. Because everyone on Discord said it should just free up be pressing and holding PZB Frei for one second (and it didn't work after pushing all the buttons and flipping all the isolating switches and everything).
