You guys need to chill a little, if the project takes 1 or 2 more weeks there is no problems, Elon Musk for example always puts impossible time limits on his projects which he never achieves, even though his team works hard!

I wouldn't try to get a new dev, i would try to strength the current team, inner fights is normal in the process of making the team better... but that is just me, you ofc do what you think is best for the platform
