Build your factory as a Spidertron from the start! Instead of unlocking better weapons and armor, unlock upgrades to yourself.
Mods introducing new content into the game.
Transportation of the player, be it vehicles or teleporters.
New ways to deal with enemies, be it attack or defense.
When I just spawn and press enter (to go in/out of vehicles) the spidertron just poofs out of existence
Edit: found the problem mod, Cargo ships mod- Probably because they have a weird way of entering and exiting ships compared to everything else.
How strange! Well that sounds like something that cargo ships needs to fix, not me :)
