First off, it's extremely rare that any game is bug-free. With every single update, there is change to code that can create new bugs. Second, as others have stated, in all my time playing this game, I've never had a bug like this (unless I'm rolling with mods, which can cause an unstable experience. But that is not the game's fault). Your experience, while unfortunate, is very likely a rare occurrence and can be attributed to many things, including any mods that you may possibly be running. Lastly, complaining can be a great stress-reliever, but when it comes to bugs, creating posts like this is pointless and does absolutely nothing to fix the issue if you fail to submit a bug report. If you already did that, kudos! Otherwise, do everyone a favor and click that red banner at the top.
