Weird bug I just found - it happened twice when I had trains stationary on the UWS/REV but now I can't figure out how to reproduce it. Argh.

I had a train stationary at W928 with the route set forwards into the occupied berth W926. A train came up behind to berth W930, and at some point on two occasions the TD for the train at W928 stepped back to W930, overwriting W930's TD. Apologies I can't include detailed reproduction instructions. Maybe if there were the ability to have snapshots at 1 minute intervals rather than 10 I would be able to

I think I can reproduce it.

A TD interposed at W928 or W929, with the TC (T1362) occupied, then another train approaches W930 and occupies TC T1360 causes the TD to step to W930.

In effect, the TD steps because the conditions are satisfied for the TD step of auto-signal W929 (trigger T1360 with condition T1362 occ) {for Peter's info, maybe a direction flag condition needed?}.

I can only help one person a day. Today's not your day. Tomorrow doesn't look too good either.
