Bug regarding the grid of buildings

I was recently working on a bigger project involving 10k+ pieces in multiple buildings (Park total ~50k). After finishing one building which was created by detaching pieces from another building the grid from the original building was misaligned. This is pretty annoying since the whole creation relies on a perfectly aligned grid.
 
How is this a suggestion or a bug? That just means you maybe didn't pay attention to the sliders for grid size while building. They do reset once you tag out of them.
