I made a post and it just disappeared ...

It doesn't exist on Steemit.com, Steemd.com or Steemdb.com.
Steemstats however shows it:

It was there for a moment in
https://steemit.com/created

I've heard this happened to a few people.

On a sidenote:
Steemit.chat doesn't load for me.
That's what my post was about.

Does anybody have the same issues ?
