Hi,
while going through journalctl I noticed the following entries from my exit relay and wanted to report this non-fatal assertion.
I also host a Guard relay on the same VM and IP, and it did not yet assert that message.
The full assert() with the stack-trace is as follows:

I will try to cooperate as best as possible, but my life is kind of messy right now.
And because of TROVE-2023-007, I will have to update the relay to version 0.4.8.10, and reading the change-log of that version, it might actually fix this assert.
Still wanted to let you guys know.
