Probably a stupid, but mostly an uninformed question, didn't we claim a few months ago? Or is there something new to be done?

If you claimed a couple months ago there's a good chance it was rolled back. So you need to claim it again using the GUI wallet.

Absolutely agree!

Please test last ver of GUI IOTA and double check if everything ok with your stake!
