I think it’s simply how the forum software works.
A bit like on youtube, the views appear only with a certain delay. I guess it comes down to caching?
Edit: but you are right, there are an awful lot in the recent posts right now.
Yes, it seems it’s the case for every thread started in May has this problem. I actually did a test on this thread:https://forum.renoise.com/t/keiss-little-big-secret-music-video/43585
It showed up as having 0 views and 0 posts, then i wrote a post in it and checked it again, now it said 48 views and 1 post. So it must be something fishy don’t you think?
