If I create a small 3x3 twig, 3 stories high structure, copy then paste works fine. If I upgrade that same structure to anything above twig, it only pastes the first level. I don't know if it is a result from the copy or the paste but it no longer works. This is makes raidable bases useless as it depends on it. Has been working fine until very recently. This is with new copies and doesn't fall under the older version pasting in another post.
