In Spirit of Steam journey mode within the Steaming Ahead section, journey number 3 Express Freight Northampton to Edge Hill Yard, shortly after starting and without any warning you apper to pass a red signal that is not displayed which causes service failure due to the SPAD. This occurs at approximately the point where the 15mph speed limit comes into effect. After trying several times, I have been unable to complete the service or understand what is going wrong.
(FTFW) Supposedly being fixed by DTG... Seems to have gone very quiet. And my hunch, is that there's more to it than the AI SPADs originally thought to be the issue. The fact the bug happens in more or less the same location regardless of what time you get there to me indicates a route problem, maybe a rogue link or trigger however the signalling system works in TSW.
According to a DTG staff post in the "Still experiencing..." thread, the problem occurs when AI drivers use turntables. Something about it triggers a SPAD condition. The fact that the issue has been known for several months now without a fix, however, is starting to get very frustrating.
