I probably posted my comment before it showed up, which would have required me to actively refresh the page to check for more comments, something I only do after I get done commenting to look for replies.
Make sure your game version is 5.1, bottom corner of the main menu, and make sure any mods that cause problems are disabled, though I suggest doing it manually so you get exactly which one is causing issues, not ALL of them, some of which you might use.
Yes and I believe Katarsys has tried to fix this leaving issue.
I would suggest it given you are a couple back, normally I would say it should be fine to just update the existing copy, but that's when you are one behind. It MIGHT still work, though.
