Tried to establish rendezvous on non-edge circuit

In #12997comment:6 nickm requested to open a new ticket if someone gets that warning again.

I get that warning since weeks on 0.4.1.6 about once a day on different relays. Even if legacy/trac#12997 (moved) is implemented i never saw a more specific warning than that simple line.

This is all the log shows me:
