The only thing I noticed crash wise is, sometimes when first starting a game, if you grab the winch "rope" before the player model actually spawns in, you will get a rolling error that will at least lock up the game until the player model spawns in.
That's a game thing and I'm not sure why it's sometimes delayed like that. Outside of that, I'd have to know what if any errors or warnings are appearing in your log file to know more.
