Updated our code to stop Fabric of Reality platforms from generating under exits all the time. Now they generate only when the supporting blocks are replaceable (in which case they're replaced by FoR) or when they're not opaque solids or have tile entities (then FoR generates on top). The exit search algorithm treats replaceable non-liquid blocks as air, so an attempt is made to build against the ground and not on top of replaceable blocks. The area around the door is cleared of blocks to avoid killing the player with lingering replaceable blocks that might be harmful, like poison ivy.
