Signal error loading old BVE4 route

I have a problem with signals in an old BVE4 route, TRTA Hanzomon line. In the beginning of the route is a signal that never clears in OpenBVE 1.9.1.1.

When loading the route, I get some errors in the log file that may be related: “SignalIndex 3 references a signal object not loaded in Track.SigF at line 516, column 2 in file…” and the same for SignalIndex 4. That is correct, there are no signals explicitly defined in the route file for signal index 3 and 4.

However, in the description of the .csv route format, it is stated: “If no object has been defined by Signal(SignalIndex), one of the default Japanese signals is used”. There is also this text in the logfile: “INFO: Using the Japanese compatibility signal set.”

Q: Why do I get these errors regarding SigF when OpenBVE should default to Japanese signals if no definition Signal(SignalIndex) is in the route file?

The issue appears to be that the actual signal object is missing (it's not loading the default in this case for some reason), and the red you're seeing is a dummy for another track.

Let me take a better look into this.

Build from today will fix this- I think that must have been accidentally broken at some point

Please note that this will now generate a *new* specific warning for this case, so error numbers on some routes may change marginally.

Thanks a lot, I have tried the latest build and now the light signals appears as expected
