Adding in empty sheets in between didn't work unfortunately, but copying the polygons to a new sheet with the same effects did the trick. Thanks for the tip!

Double check your layers and sheets if you have 'text' hidden.

Also check your current font size, maybe the text is too small to see.

Was it this map?

I went back and made some more maps for Alternity, this time trying out a different style. I'm planning on using these as player handouts.

I second this. I used Cosmographer deckplans for vault-like maps to recreate Gamma World maps.

You could perhaps also use SS3 Modern Blueprints to make maps like this:

If I could make a suggestion, I'd love to see a sci-fi/deckplan style for Perspectives 3.
