I would say this is an edge case, it was reported before.
Our ember router and discourse server router are in slight disagreement about what to do here.
Relying on slug that is ever changing for routing a topic is super fragile anyway. If we rename “welcome to meta discourse org” to “welcome to meta discourse” this would all break spectacularly anyway.
Don’t remove the topic id if you need stable links is the lesson. The topic id in that case is 1, it is not a post id or number.
Ok, ¡gracias! Entonces, si quiero que el ir y venir interno funcione, ¿realmente necesito conservar tanto el slug como el id? Porque usar solo el id parece no funcionar: https://meta.discourse.org/t/1
