I used to play on a Windows machine, but recently switched to a Mac running Sierra. I installed the SDL2 framework as suggested on the forums, then downloaded the Mac installer from Sourceforge. Ran the Unix executable file and modified simuconf.tab as suggested on the forum so I can use addons. I copied over the contents of my maps, addons, and save folders from my old computer, and they show up in the heightmap and load menus in Simutrans (and the addons are getting used in the pre-generated game that appears on startup, so I assume they are working as well). I can run Simutrans and can start a new game, but whenever I try to load a saved game from my old machine, Simutrans gets stuck exactly halfway through the "Destroying old map" progress bar. My Mac slows to a crawl, the cursor turns into an hourglass, and within about a minute or so, Simutrans quits. Any ideas what's going on? The last few lines from the command prompt thing that runs with Simutrans says:
Calculating textures ...done
Loading BDF font 'cyr.bdf'
Running world, pause=0, fast forward=0 ...
FATAL ERROR: loadsave_t::read - savegame corrupt, not enough data

I suspect that because I am able to save a new game on the Mac and load it successfully that there is some compatibility issue with my Windows version .sve files and the .sve files created by the Mac. Is there any hope for my old savegames?
