Whoa...! I was editing one of my community documents, and suddenly the whole community disappeared. Can you help?

My community is:https://lemm.ee/c/eurographicnovels

The post I was working on was:https://lemm.ee/post/2890991

To be clear-- I, in no, way, shape or form intend to delete my community. I wish the community to remain undeleted, thanks.

In case it matters:

EDIT: Google retains the specific URL's of a bunch of our posts, such as the "Moebius" ones.
