For some reason, every time i try to add a game to my wishlist, it asks me to sign into my account. this is fine, aside from the fact that im already signed in. upon following the promt to sign in (again), i can click the wishlist button, and it will ask me to sign in again, maybe i should switch to firefox? im also using tampermonkey, which ive seen cause some issues with some sights, ill remove it and give it a try but im not sure it will be much help.

A bug, perhaps?

You might be logged in on another PC or browser.

Try the "log-out" all button over here: https://www.gog.com/account/settings/security

so i believe i have solved my issue, i think it was some sort of glitch, i used a workaround where i would add a game to my cart, and move it to my wishlist from there, now for whatever reason im having no issue with adding them from their store page.

It's an okay work around, but unfortunately that won't work for games that are current TBA. Speaking of games that are TBA, I recently found that when going to their store pages, the add to cart button constantly switches between "Notify me" and and a three dot buffering symbol; clicking on it just gives the same sign in issue plaguing the wishlist button.

There's a good bit I like about GOG, but in the short time that I've used their services, the website has been growing increasingly dysfunctional. I really hope this gets fixed, but given the automated support ticket response I received, I don't really expect this to be resolved anytime soon.

Sometimes things don't work well here during sales, due to server issues or maybe PC issue if you have been viewing a lot of game pages. That last is caused by website bloat ... too much has been loaded into memory and hasn't yet been reclaimed etc.

Try restarting your browser, or doing that after logging out first, then log back in. A PC reboot may also help fix it.

However, it may just be your timing, and the servers are overloaded at the time.
