A while ago I made a thread saying that planes are way too close to the ground to be considered "planes". Apparently the game decided to spite me and make planes go UNDERGROUND. This isn't just on metal planets either, I've seen it on all planet types and believe me, it may look funny but it's actually quite annoying. Especially in forest biomes, if you tell air fabbers to build in forests and they go underground, they'll have a lot of difficulty in removing the trees, making things most inefficient. I'm not even sure what causes this, I haven't seen it until today, no one's made a thread here OR on the bugtracker, so for all I know this is a first. Has anyone seen this before? >inb4 sandworms confirmed
