Edited posts get removed?

OK, since there's no proper place to adress problems regarding the functionality of the forums, I'll just post it in the same category as where the bugs happened.

It seems that every time I try to edit a reply, when I hit "post" in the edit window, I get redirected to the "threads list,"  where you see all the thread of the category you're in (not sure what the proper name is for that) and when I then go back to the thread where I wanted to edit the reply, the reply is gone. This has happened quite a few times now.

Also, in one of my own threads, I tried to edit one of my replies which I had selected as a solution, so now that solution is also gone and the link in the thread that says "go to solution" is now dead.

Is anyone aware of tthese bugs?
