I have not seen anything like you describe so far. Regardless if there are progress breaking bugs they are very rare and usually fixable just by reloading or restarting the mission. Thought could be just a bug introduced in the last patch, that will be likely fixed in the next one.
Still, claiming the game is unplayable is completely misrepresenting the actual state of the game in my opinion. Also patches introducing new bugs, or games not being completely bug free is pretty much inevitable in software design, you should not insult the devs for making their jobs.
Regardless, who are you complaining to? We are not devs, nor we represent them. This is a community forum, not a feedback tool.
There is an actual feedback tool, and there is an actual in game bug report system. Use the proper tools to report bugs. Also being polite, accurate and not using exageration or personal attacks may actually help, if what you want is to actually report a problem for it to be fixed.
Also, cherrypicking two separate issues from your experience, connecting them in your argument for no reason, and argue for the bad faith of the devs based on that imaginary conection, is not a good argument. That is not how reality works, and is an accusation in bad faith.
Finally, expecting a problem you just reported to be inmediately fixed, and starting to use personal attacks, discredits your position and removes your credibility. Don’t do that if you want people to help you.
