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

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:
