Can we please have a warning and an estimate of what types of building elements are going to be destroyed/despawned/eliminated in the new version?
I think this is important because the last patch changed the height of triangular foundations, resulting in the destruction of all placeables that rested on them. The patch before that changed the support struts from functional into decorative, resulting in the collapse of all floors that received their stability from them. In both cases, the damages were substantial to a lot of people.
With some advance warning, we could at least remove any chests and workbenches and their contents from endangered building elements.
It would have been a good idea NOT to wipe the testlive servers before patching them, so that testers could observe the effects the patch has on existing structures, rather than players having to find out after the fact, like in the past.
