TEST ENVIRONMENT
PC; Win 10. No mods

ISSUE
This was an interesting one to troubleshoot... Undoing a placed blueprint which includes items in containers (ie chests/turrets) normally if single click+placing, allows for a single action undo for the entire blueprint. Drag-placing though, undoes the placement of each set of items in each container. Seems like instead of seeing the blueprint placement as one component, it breaks the task into sub components

STEPS TO REPRODUCE
1. Create a blueprint which has a few turrets each filled with some ammo. Easier to see with snap-to-grid enabled.
2. Drag-place the blueprint (can be a single instance but just drag placed or multiple instances of the blueprint)

EXPECTED BEHAVIOR
Should act like the single non drag option by undoing one entire blueprint placed instance in one go.
