Recently came back and found some great updates, the new visual improvements are killer.. however on my first new world, it has a travel requirement of molenests, and with no more things to research.. I still can't purchase mole nests, tho I do have moles, and they show a constant upgrade flag without having anything to upgrade under them.. is there some missing feature I'm missing or are mole nests not fully implemented yet?
updated, now you should find a new research
