So I was making my scenario on Spirit of Steam (starting from Speke) and using the 'RF 37/5 x2 + BBA Flats x12' and I load it up... But when it loads up, the 37s are all replaced by 20s. I've tried reloading the scenario multiple times and they keep switching between 37s and 20s. I'd not even used a single 20 in the scenario, so far it was all the same 37 consist and all of them kept alternating. I'm no expert but I don't think this should be happening.
