- Create a blueprint containing items that must snap to 2x2 (suck as rails) and items that don't need to snap to 2x2.
- Enable absolute snap-to-grid, and set the x an y values to ODD numbers.
- Save the blueprint.
- Place the blueprint. Notice that it places correctly.
- Edit the blueprint and "select new contents for the blueprint". Select the same contents as before and save.
- Place the blueprint again. Now the non-snapped objects are off by 1 in both the x and y directions (in fact some elements are overlapping)! See ghosted objects:
Based on the first and second screenshots, it looks like the blueprint builder is choosing different origin points depending on whether this is a new blueprint or an existing blueprint. It should choose a consistent origin.
