Riot/Matrix room

@zottel & @Andrew Manning & @Camron B  & @paulfree14 & others who hang there, I get:

Room '!' does not exist

Where did it go?

Very odd.

Room '!' does not exist
This is frustrating. I can't get out and can't get in.
So @Andrew Manning invited me to (re)join and I'm back. I have no clue what happened.
