Bug when moving objects that snap to differently sized grids

[Sambo]

If I move, for example, some tiles and scenes at the same time, the tiles snap to a 32 x 32 grid and the scenes snap to a 16 x 16 grid, so the scenes end up placed wrong sometimes after moving them.

This is an old imperfection which I'm not done.
The snap must be applyed to whole selected group, but applying to each item, also collision check is too slow on big maps because collision checking for eacjlh item. I will take care for end this work before Beta of the editor.
