Just make a thread HOW TO FIX WITCHER 2 STAMPS (in all caps) and bump it evey few minutes... ;-)

Same here. It's not letting me click on the 2nd stamp and the timer has about a 24 hour wait.

Yeah, just logged in and the Timer is reset and it says I've collected the Stamp - which I haven't, nor did I have the option too do so.

Just log out and back in again :-)

If you see that your first stamp is gone, just click it again and the second should be unlocked.

I clicked 1 stamp yesterday
just now I refreshed the page and Witcher 2 stamps still shows over 23 hours and 40 minutes to the next one unlocked but I cannot click 2nd one now ....
Looks like counter was reset today and I should be able to claim my second stamp 20 minutes ago but can't click it (shows it locked)

edit: I will try logging out and in again later today to see whether that fixed it

PANIC!!!4!!44!!!!!!

Thanks for that. Logging out/in again works for me and both stamps are showing.

Logged out, logged back in, clicked the FIRST stamp ( [+] ) and now I have two.

Must be bad coding, but it does register eventually.

Worked for me too. I logged out, logged back in, and clicked the first stamp to get the second one. I hope GOG can fix this bug!

I experiemented a little.

1: When I'm logged in and refresh the main page, I have one stamp (yesterday's) and can't unlock the second.
2: When I log out and back in I have zero stamps. But clicking the first will activate the first two.
GOTO 1

It's always the same, regardless of browser.

hmm...but I basically had this issue on Day 1 (but thought it went through despite seeing the lock), so logging out now and logging back in just seems to give me only one stamp period.

I'm not up in arms if I don't get it but it appears I'm "officially" a day behind.

Did you click on the first one again to see if it would unlock the second one?

That did the trick. It works for me now.

yes
