This was appearing in various launcher versions also before but seemingly randomly.
I think I can now reproduce this - after manual refreshing of server list (continuously pressing refresh for 30 or so times quickly) - yes I am doing it sometimes to get onto an only server with players which often seems to be full - the player list always shows “loading players…” but to no avail.
Also mentioned briefly before the unimportant typo on the map picture in launcher: Stop Watch instead of stopwatch, now also noticed Death Match instead of deathmatch, but this is going to be corrected in a neext one as far as I understood
