Detailed Description of the Problem: Every time I receive notification about people posting on my listing discussion threads I receive two copies of notifications. See screenshot. Same happens for other people's games where I am a player. Every time someone makes a post in the thread I get two notifications. Does not affect notifications from private messages, it seems. Started yesterday (11/27) after the site broke down. This is not gamebreaking in any way, but it is a bit annoying. Steps to Reproduce the Problem: Since it happened about a dozen of times already, I assume just posting something in the thread of campaign would trigger it.
