Mogstation - Steam Account Unable to pay with anything but Steam Wallet

Ran into this issue this morning with payment method through Mogstation while using a Chromium-Based Browser. I've found posts were people encountered something similar in the past. My primary browser is Vivaldi (A Chromium Derivative). I decided to try another browser just in case it was due to using an unsupported Chromium Derivative and Chrome itself worked fine, all the buttons were there as normal for paying with the subscription.

I had already added Crysta (my preferred method of payment due to no overdraft charges) through Vivaldi, but when I went to try and pay, only the pay with Steam Wallet option was available. Thinking it could be an issue where if there was not enough Crysta it would not show the option, I logged back in via Vivaldi (after having re-upped through Chrome while I could) and the only option was still the Steam Wallet.

Thought I would share this insight/mogstation payment bug to potentially be looked into.

sorry for the huge necro - but i actually had this happen to me today on firefox 94.0.1 64-bit. i couldn't find anything about SE cancelling crysta payments for steam users, so panicking after paying for crysta and not having the money for any other form of payment due to unemployment at the moment, i frantically searched for solutions and found this post. That gave me the idea of clearing my cookies for the mogstation website, which promptly broke it and gave a "down for maintenence" webpage for it, forcing me to revisit and relog into the mogstation... and lo and behold, there were the normal payment method buttons.

So if you get this error, try clearing all your cookies for the mog station and reloading/relogging into the mog station and see if that fixes it for you - it might be your browsers coffee biscuit has started to go a bit off. :P
