Invalid grid alignment

Problem Description

When i have added items to the layout, and have teh grid on it may appear all aligned correct.

I then press cntl, and drag to make a copy object and change its size, it still appears fine.

however when i now move this object it jumps to between the grid lines.

Hard to give an exact example as i have copies of copies but playing around with making an object from size 100, 600, then clone it and make it 25,600 on a 25 grid and it does off grid.

origins are all correctly aligned.

A good test actually, make a 25 , 25 grid.

then make a sprite, resize it to 25,25, check origin is 12.5 and fill it black. on the layout it now sites between your grid of 25 lines.

hmm, actually it aligns to origin, so maybe this is user error?

however I have also noticed that at somepoint set objects of a set size seemed to change, for example earlier parts of a level made with blocks at 100x500 becaome 102x504 . ? Only thing i can see i could of done to cause this is turn the grid off for a while, should premade objects then change if you do this?
