Message history randomly disappears

[richvdh]

Steps to reproduce

1. Open "Office of the Matrix.org Foundation" https://matrix.to/#/#foundation-office:matrix.org
2. Scroll up until about 12:00 UTC on 15/6/25

Outcome

What did you expect?

Ability to view message history

What happened instead?

Timeline suddenly jumps to 11:00 UTC. When you scroll down again, it only goes as far as 12:36 UTC (i.e. the last 24 hours of history are completely missing).

Operating system

Will you send logs?

Yes

[richvdh]

Well, I would send logs, but that too appears to be failing, with Uncaught SyntaxError: Invalid or unexpected token (at 3075.js?1750070319043:1:6)

[richvdh]

ok, sending logs works again after restarting Element
