Thank you for watching this and helping out here. I wasn't sure if GOG staff is still watching this very important thread anymore. Now we can be sure that complaints about such things will not go unnoticed. Good job! Maybe you could also forward that update flags are missing completely now since quite a long time, would be great!
All the games reported - ITTA, The Great Perhaps and Heroland - now have their forums and are linked to their game pages. Thank you both again for reporting it.
As for the missing update flags, it has already been reported. If i have any new info i'll let you know.
Do you know whether GOG support are working these days?
I have opened five tickets in the past month (April 14, 19, 22, 22, 26) and have not received any non-automated reply to any of them. All are still marked as "Open".
They are all bug reports, so not too urgent, but still, two to four weeks of no reply...
