OK, so there's a third patch for you to test. I'm going to name the next build V16.5 just to save confusion (though it won't help too much as the launcher text won't update from V16.1, so never mind).
Before I release it on Desura, I want to test it here a bit more. I have produced a third patch in an attempt to fix the Farm crash bug.
To apply it, you need the latest V16.1 standalone (or Desura client download), a clean copy if you've already been applying the earlier patches I've made. Then grab the patch here:

Once you've got it, run the .exe and then start a fresh game (it won't cure existing crashing saved games) and report back if you get any CTDs. I've removed the two earlier patches from dropbox so everyone knows they're getting the right patch, but it's called V16.5 this time around.
