TD render fix 2: Electric boogaloo

This fixes TD's terminal stage freezing the game in a similar manner to Lava Mountain, except this time the FOFs aren't zero-height so it's a slightly different situation?

makes sense

I can't see anything that would break from this, I'll make sure to check that the crash is fixed when I can, thanks for the help.

Status changed to merged
