I've been having an issue in placing floor or wall tiles. What I want to do is place a line of tiles, group it, copy, and paste. So I carefully (frequently using alt) align my tiles, select them all, copy them, and then paste the group. And then it all falls apart. The minute I click on the pasted group the tiles fall back out of the alignment I put them in, snapping to the grid in some strange way that doesn't match the way I put them and pulls them out of alignment with each other. Align to grid doesn't seem to do anything except stretch my tiles in strange ways, especially when I want to use tiles that are smaller than a grid cell, such as a wall. Is there any way to make this work?
