In coding, a Dev fix one bug and with that fix more bugs will appear, is not the Devs fault.
This is a game in early access testing a beta version of an update, is normal to have game breaking bugs, that is why the player base volunteer to be beta testers, to help the Devs to fix the bugs before the live version, there is no need to be rude to them.
A bug fix may result more bugs, is hard to control that.
(any Games Developers correct, if I'm wrong)
