I just posted a Sidemail.io milestone and after clicking the "Save" button nothing happened, so I clicked it again, still nothing... So I clicked it a few more times, and again nothing happened. Ok, this is some kind of a bug I'm thinking, I have to do it all over again. I went to the bathroom, came back and sew the milestone was suddenly posted like 5 times. I kinda freaked out. I immediately deleted the duplicates.
A disabled state for the button while submitting or something similar would be ideal.

I just ran into this as well when submitting a normal post, so the bug is still around fyi @csallen
Definitely seems to be a bug that was introduced recently, thanks for the heads up.
Seems to be happening also for other posts I guess, many duplicates lately.
(The generic site speed is much better lately, thanks)
