[CLIENT] or [CRASH] - No post-game screen coming up.

Just looked at How to Submit a Bug, and I did not know whether to say it was exactly client or crash, or if it is even really a bug since I do not know these sort of things... but anyways...

The issue I have is that the post-game screen with the stats and honoring does not always pop up after my games. After clicking continue after my victory/defeat, I get sent back to my desktop with nothing, absolutely nothing. League is not running anymore, and I have to re-log back to the client.

Other than not being able to honor (unless there is another way I do not know, since I am still new-ish), it is probably not that big of a deal. It is just mostly annoying.

Originally, I thought it was just crashing due to longer games, but it has been happening more often recently since the last update I have installed. I have no proof of this occurrence, and though I have asked many times in-game, I have not had many say they have had the same problem... But if this could somehow be fixed or I could be given a solution, I would greatly appreciate it.

(Sorry if I may have rambled or got this whole bug-report thing wrong...)
