Well that's going to get expensive.For some reason, you cannot merge two grid-locked groups. And facilities are grid-locked ones.
You'll have to add facilities by editing the new group, but you cannot add existing ones.
I was demolishing a building and wanted to rebuild without having to buy new facilities.Is there a particular reason you want them in the same group?
I already split them from the group. And when adding facilities into a new building I can never get everything lined up right. Either construction pieces don’t line up right or the paths don’t line up right. I just deleted the facilities after finding out I couldn’t regroup them.You can mover the facilities into the correct position using advanced move without having to group them with the building itself and they will operate just fine. Alternatively, demolish the old building leaving the facilities, and then build from scratch.
