i brought the new building skin and when i upgraded to stone it worked when i upgrade metal all hqm it takes the cost but goes back too twig

Having same issue - upgrades go to twig but take higher lvl resources

same here 

Just tried it out on a 6 foundation base with walls , it was of course twig (0) , i upgraded to (1) then (2) then (3) then (4) and back again through each level back to 0 several times without any problems, it did not jump levels back to twig at any time.

Did u ever install Building Skins plugin? on codefling? i installed that and then a week after noticed issues i have since then remove that plugin and still have issue i did the same last night and when to upgrade a 1foundation with 4 walls and a roof did the up and it didnt up grade it just did the animation and stayed twig if i upgrade one by one and up grade it reverts to twig..
