I have recently installed the Discover University Expansion and now when placing windows it will not give me the option to place them singularly and not in a group for the whole room. I know it’s not my controller since I when paint the walls it works. I don’t know if the game is just being weird or what. It hasn’t given me the chance to change it since I installed it.
Someone reported this on the bug forum, and it's apparently a glitch introduced in one of the recent updates. If you go to the part of the menu where you select the window sizes you can still adjust the placement mode there, so you will have to do it there for now. Another thing I've noticed (and I'm not sure if it was always like this or not) is that if you place wall or floor patterns and change the placement mode in either of those, the setting will stay active which means if you select room placement for the floors or walls it will carry over to windows as well. If you keep both of these things in mind it's not quite as annoying, though not being able to swap placement modes while actually placing windows is still annoying. I hope that helps in some way.
