Daynarr,
Yes, I am using a custom map, which I'll attach. I am not, however using any mods. My SE4 game itself is totally plain-vanilla
Yes, it is almost certainly related to use of the map editor. But what the heck, I mean, it's a new SE4 toy, of course we're going to play with it until it breaks
Thanks for asking, Daynarr, you're one of the good guys around here.
