The nightly from 18 June () caused merry chaos with my signalling system. I don't completely understand what happened, but the most likely explanation is that previously, if you rebuilt a single track line as double track, the token block signals functioned happily as faux absolute block signals. Now they stay permanently at danger when on a unidirectional line. It probably makes more sense, but anyone else who's tried to save money this way, beware!
Thank you for your report. Can you upload a saved game in which this issue can reliably be reproduced at a specific time and place?
I'm not sure that there is an 'issue' in the bug report sense. I think it's more the case that I was exploiting a loophole which has now been fixed. But I need the game to run for a bit longer before I understand whether the chaos was transitional or permanent.
I see. Can I check whether anyone else is having trouble with token block signalling?
I do perhaps need to produce a video tutorial for this signalling system quite soon.
