LocoSwap just core dumps when Im trying to swap default SD40-2 to something else. Also loco image is not shown in scenario selection menu in game. Can it be fixed somehow?
These scenarios are in a legacy file format. Before you use LocoSwap, load each of the scenarios into the ingame editor and resave them - this will update the file structure automatically and will also enable the loco preview (which is not defined in the old format). You could also just clone them in the Build>Scenario menu which will apply the current file format. Make a backup of the route's scenario folder first.
Thanks, editor resave method works! Why authors of paid dlc do not do it themselves I wonder... After all they do not completely compatible with current TS steam version...
Because it is legacy content and the scenario format is accepted by the game. That someone would need a 3rd party LocoSwap tool that cannot handle these files in the future was not foreseeable.
And there's always a slight risk of breaking very old scenarios of sufficient complexity when resaving them due to dispatcher code changes - in any case it would need time-consuming retesting of each scenario.
