I imagine this almost never comes up, so it would probably be hard to test, but it actually did happen for me. If Bubble movement results in a match of 4 gems, I get the popup text for an extra action, but don't get an extra action. I'm not sure if there was some other factor that prevented it somehow (not sure what it would be), or I was supposed to get an extra action, or it's intentional that Bubbles can't trigger extra actions (and therefore the error was the text popping up).

Any effect that happens before an action is made cannot grant you an extra action, so that seems to be a mistake. I think we correctly not giving an extra action but the popup text doesn’t take that into account yet. I’ll make sure to fix this to remove any confusion. Thanks!
