Board Game Arena

The way to do this is to click on a commodity in the resource pool,I think.However,the system does not explain that.It does,however,offer a very prominent button allowing you not to select an extra commodity.I just accidentally clicked on that,because I couldn't see how to select the extra commodity.Since players probably will want to select the extra commodity,I suggest that alongside the button that you probably don't want to clickon,you say 'if instead you do want to select an extra commodity,click on one in the resource pool'. Then people may not make the mistake that I just did !
