My builds have had components disappear twice now on this realm, and it has been with my auto chicken farm both times. The roof and the interior of the device was well lit, as well as the cow pen and the rest of the surrounding area. This does not appear to be a creeper explosion, as both the side of the cow pen and the other side of the chicken farm were affected, without destroying all of the central chicken farm components like all 3 dispensers. I have no clue what could be causing this issue, as both times this has happened I have been out of the chunk the issue occurs in for an extended period of time (maybe 3-4 in game days?)
