Hey there,
I'm looking to use your "Launch Pad" for an idea for a new factory I've been working on.
Found an issue though when the Spidertron is instantiated. It doesn't register the new entity with the game properly so other mods don't know that a new Spidertron exists. "it doesn’t raise the script created event" is what I've been told asking around.
You can see this with another mod called "Spidertron Control Center". Just run that mod (it's really helpful to have anyways), manually place down one Spidertron, then have your tool instantiate one, then manually place another down. The first an the last Spidertrons will appear in the "Spidertron Control Center" but the one your Launch Pad gave birth to does not :-(
Any chance you can take a look at it?
