RESOLVED: Seems language undeterimed was causing the issue. Hitting back in the browser (in old.lemmy on chrome) retains the post contents. All I had to do was select English and resubmit.

…

Yea I just spent like an hour typing out a submission and when I hit submit it just dissapeared.

I honestly am so disappointed.

Can someone help me figure out what happened? Was it because I didn’t select a language??
