problems with Fantasii V2 activity

[johnnyboy99]

I've tried playing the Southbound Manifest Activity for Fantasii V2 and i've run into problems with it. More specifically, whenever in autopilot mode, at a certain point of the activity when I reach certain crossings, it crashes the game as it reports a Null Reference Exception regarding the some crossings. I tried going manual and went a bit further, but as I wait at the red signal it still gives off the error. How do I fix this?

The log file (OpenRailsLog.txt, on the desktop) should have some information on what could be the problem.

I would but I overwrote it after playing another activity. I know it involved one of the crossings somewhere before Ivanhoe

Run it again

[johnnyboy99]

you didn't have the same problem with the activity?

[johnnyboy99]

more specifically the error had something to do with AI horn triggers at a certain crossing

here it is

If you want help, attach the log file.

[johnnyboy99]

it says the log file is too big to upload

[slipperman]

Then zip it up, dear Liza, dear Liza, zip it up !!

[johnnyboy99]

OpenRailsLog.zip here it is

whoops meant to post this in the screenshots thread
anyway I think I need to edit the .tit file because there might be an error there

[c44d9w]

This is the code that causes the exception:

        public override IEnumerator<int> Execute(MSTSLocomotive locomotive, int? durationS)
        {
            if (!durationS.HasValue)
            {
                // Sound the horn for a pseudorandom period of seconds between 2 and 5.
                durationS = (DateTime.Now.Millisecond % 10) / 3 + 2;
            }

            locomotive.ManualHorn = true;       <--- exception thrown here
            yield return durationS.Value;

            locomotive.ManualHorn = false;

            if (locomotive.DoesHornTriggerBell)
            {
                yield return 30 - durationS.Value;
                locomotive.BellState = MSTSLocomotive.SoundState.Stopped;
            }
        }

This implies that the field "locomotive" is null. That seems rather strange.

But then, the log file also contains the following warning, implying that there is a train with no locomotive.

Warning: Train Fv2_SB Manifest Trf 07 (23) has no locomotive!

oh, I forgot to swap that out with a freeware Genesis
