Thanks!! @[email protected] @[email protected] I just fixed it as you were testing/commenting just now, which is why you were both seeing different things. I should have let you know I was fixing it to avoid confusion.

Turns out that a bug that I fixed recently caused an error instead of a warning for a certain class of problem. Now it should show the warning instead of just breaking the gen.

Thanks again! Please let me know if you run into any follow-on problems. Also, you might need to wait a minute or two for the cache to clear before confirming that all is back to normal. A quick way to ensure cache is cleared is to make a small edit to your generator and then save it, and refresh the page.
