How come I'm not allowed to get extra tokens....

I'm the screenshot, other gems are highlighted so I guess you are able to grab them, no?

The way I understand you are trying to take the red token and only that one

They wrote right above you that this is wrong.

Thanks all. I'll post a bug.

I just re-read the rules and the publisher's site says:
"A player can never have more than 10 tokens at the end of their turn (including jokers). If this happens, they must return tokens until they only have 10 left. A player can return all or some of those they've just drawn. The tokens owned by a player must be visible by all players at all times."

So it's not tokens + development cards.
