Pages with data, like “Players” or “Player profile” was being excessively browser-cached: for 2 days. You had to press F5 to update your data after you uploaded your replays.
It confused a lot of users, and now it should be fixed. Now this browser-cache is set to 3 seconds, and above it there is a static server-side cache for every page. Static cache is reset every time actual new replay was parsed and data has changed.
TL;DR: you won’t need to press F5, now it should work just like any other proper site on the internet!
