Crash Fix — Pub Sim Steam update #659479

Hi everyone and apologies for taking so long to fix this one, it was a real pain to find and especially over Christmas. However, with fingers crossed, we believe we got it. We've included a bunch of optimizations as well which should reduce the filesize by roughly 2gbs. Ultimately it was an issue to do with an unused save file not updating properly and causing a crash as soon as the map was loaded. Since we load the map upon game start it caused an immediate error. If of course you're still crashing or find other issues then please let me know and we'll be right on it.
