Hiya Sam, I’m replying as a user of the same site as snart who has also encountered this issue.
We’re not fully sure of discourse terms yet so apologies if I misunderstood your question. The page trying to load multiple times issue does not happen when tested on meta (I’m assuming meta means this particular site?).
On our site when we click on a topic it will load it, but a few seconds later the page reloads itself despite having already been loaded. The browser we have noticed the issue on is Chrome.
If I still haven’t explained it properly I could try to upload a screen recording of it, if that would help to clarify things.
