The most unhinged ways to transport items and yourself around your factory. Fling items around with Thrower Inserters, launch your trains off ramps, and soar through your base on electric ziplines!
That's probably because of a rocket, grenade, capsule or some other thing the code is trying to generate a primed projectile for. Are you using any mods that add something like that? If you can let me know I can try and add some checks to make it more compatible
Looks like both those mods have capsules that dont function like a traditional one so it messed up generating a primed projectile version of it. I added some checks that exclude them and everything seems to work in the new version i uploaded. Lemme know if you're still getting problems
