allow us to sell seeds, like maps, at vendor

this has been commented on many times, that seed drops are totally skewed. have been getting at least 3 vivid to 1 of either other color since the start. currently sitting at 132 vivid to 44 combined primal and wild and that's after growing some extra plots of 24 vivids.

please, please create a vendor recipe, similar to maps and other currencies that allow us to trade in all those extra vivids for primal or wild. maybe something like selling 3 of the same level of one color gives you a seed of that level from one of the two other colors. or trade 2 of the same level of two colors to get a seed of that level from the third color.

I am getting totally stuck trying to harvest tier 3 seeds for lack of life force because I get yellows at a 6:1 rate to either of the other colors. this, more than anything else, is making the new league very unappealing to continue
