That would explain it. The Inkan client sends the 31045 timestamp events to the Inkan relay automatically while you are logged into the client.

So when you log in the next time, you may not immediately see the regular events you posted since the client won't find their timestamps on the relay at first. However, it should catch up over time as the 31045 events are getting posted to the relay and the client can then later retrieve them. So they should become visible again after a while.

If you use another client, the important thing is to include wss://relay.inkan.cc among the relays you post to (it looks like you are doing this!). If your events don't end up on that Inkan relay soon after their created_at, they don't get timely OTS timestamps at all, which makes them forever "invalid" from Inkan's perspective.
