Just had this for the first time (to my knowledge), didn’t get a notification of this: http://forums.warchest.com/showthread.php/38432-so-i-just-got-an-email-for-the-beta?p=482143#post482143
I have this issue quite often, last time it happend in my Nexus 5 Thread in the offtpic section.
I’m getting this behavior very often since a couple of days. I would say I just get about 1/4 of the notifications I should get. Mainly the notifications when I get quoted are missing.
Noticed it today for the first time on a quote.
