This just hapened to two different threads in two completely different sections of the forums.
Both threads I had previously read. The overviews told me that both threads had one new reply by a user called aloishammer. However upon opening the threads I find, that said replies are not there. After that I opened aloishammers profile to find that he/she has never made a single post in these forums.
This is a new account I had to create, because the old one does not work with the new forums.
