[OPEN] Platform affecting roofs

Hi!~ Idk if you have figured it out, but I had this issue myself. It caused the roof and issued with the above floor if it was lower floors. What you have to do is place the platform, then go to the story above it, there should be a yellow outline, like how the selectable stuff is, click that and you should get "Remove ceiling" and it wont remove the floor above, it will just remove the ceiling option for the platform. Hope this helps!!!
