Since 3.6.0, when I host a game with multiple network players, while the game loads the screen tends to freeze for several seconds while the game is being prepared.
The loading screen says "Waiting for players: ..." and increments the number of seconds the server has waited for the other clients to get ready. In the past versions these increments were listed second by second, i.e. with a stepping of 1. On 3.6.0, the stepping is much larger, I end up with the screen freezing for 5 to 20 seconds. Here's an example of the # seconds listed on a game I hosted today:
0, 7, 14, 18, 38 (there was one last number, but it showed only very shortly and wasn't possible to see really).
I did like it when every second was displayed, at least having a regular update interval which is enforced would be nice to have, i.e. a 5 or 10 seconds stepping. Right now, you can just guess whether it may still be loading or is actually frozen. And a 20 second freeze can make me worried.
