Duplicate new comments notification

Hi, i would like to report that im expiriencing a bug of notifications about new comments on forums are getting duplicated.

For example, i followed this forum and someone commented on it. I got 2 notifications for that one comment for ONE thread. Currently i dont have a screenshot beacause i read those notifications, but when i read only one "x new comments" notifications they both went gone, not only the one i clicked on. I also saw another user screenshoting this peoblem in another club.

Please @Martin_Stahl let the staff know about this bug, thanks.

EDIT: i just screenshoted the bug:

I haven't seen any issues recently with duplicate alerts. 
One thing that could happen is someone created a topic (or content that generated an alert), deleted it, then created it again with the same subject. That would generate multiple alerts. Also, multiple posts with the same subject would as well.

It happens a lot nowadays for some reason.

Its not that, the thread is still there, undeleted+i saw it on multiple threads, not just that one, and that thread is only one, there is not more of them like when you press post button multiple times, just follow few threads and you will see it sooner or later

same happened to me

I have had a few today. Staff are aware of it happening and looking into it.
