Sometimes, when checking messages from a friend on web version, the game crashes. An alert appears that says:
"An error occurred running the Unity content on this page. See your browser JavaScript console for more info. The error was: Uncaught RuntimeError: memory access out of bounds"
This consistently happens when immediately after logging in, I click an online friend on the friends list. It does not occur if I click an offline friend before clicking the online one. I get the crash when checking friend messages at other times, but it doesn't happen consistently then.
