Halo 4 Forge Problem

There’s 2 problems I’d like to report.

For one currently, my map won’t generate dynamic lighting so my map is all bright right now. Anyone know how to fix this?

And for the second one, in Erosion. The block 3x3 flat, since bsangel said all magnets are hand placed, I assumed there has to be a couple of magnets that are off which is the Block 3x3 Flat. One of the magnets are completely off.
