I'm encountering an issue where interior walls drawn under a flat ceiling plane, but near a sloped ceiling, are stopping at the rafters, instead of the ceiling plane. It makes no difference if "Stop at Ceiling Above" is enabled for the wall objects. Is there any way to get these walls to stop at the ceiling plane? It's very easy to recreate this issue, but I have attached a super simple plan that demonstrates it.
Note: There is no issue when there is a normal automatic ceiling above. To recreate the issue, I have to turn off ceiling above and then manually create a new ceiling plane that is higher than the top plate. Using version X8.
