When logged in, on the GOG Forum Community page, the section labeled "Topics I've participated in" used to have a [show more] button.

About 3 days ago I noticed that button was not there. It's still "missing".

Is it missing for anyone else? Or is this a "it's just you" situation?

I still have it.

Hmmm, interesting.

There is also a "Hot topics" section and the [show more] button is not missing here. Only the other one. May have to try a different browser or something..

Thanks!

Yep,it's there..

If I recall correctly, this might happen once in a while and it effectively erases all your participation history, hence why you don't have the "show more" button.

It's still missing; so it seems likely that your thought may indeed be correct. Dang..

Sorry to bump, but I just found out why this happens. It's when one of the threads from that list gets deleted.

That probably explains why my button disappears after 3 clicks...  Thanks!  ;-)

Happened again, sometime during the sale.

I was hoping it would return after the sale, but alas, thus far it has not.

Oh well... GOG, we love ya, but ya far from perfect :)

You know, right at the top of this page, when you scroll of the way up, shall be under support a button called my posts. Click on it and you will be surprised ;)

It will lead you to:

If this is what you are looking for XD

Thanks; but that seems to have the same affliction - it only goes back to last week.

It's just one of those things..

Might have to do with cookies. exceeding a certain length/time....

I don't think that's it - because I always browse in "incognito" mode - hence all cookies and cache and everything is all-cleared every time I exit the browser (which I do frequently).

It's something else - I think it's server-side.

My updating this thread is for future reference to give me an idea how often it occurs. Not very often (so far), thankfully :)

I thought I had an idea:
https://www.gog.com/forum/general/download_purchase_history_as_csv_xml_json_or_similar

But seems not to be the case for posts, unless you can spot something similar? (a wee bit of brainfreeze in the moment ;) )

May I suggest reading this very thread?
