I have a large base, and decided to place two trebuchets on two different (but connected) platforms made out of T3 square foundations. The trebuchets were fine for maybe a week or so, after which they disappeared overnight. Someone else a few months ago reported probably the same issue on reddit, and this seems to be some sort of a bug, as trebuchets placed on foundations should not decay apparently.
