Old title: After opening the cartridge hub with both inputs at the same time, the first input is now a clone
Playing with split inputs, input 1 was Finn with a black hat and specific cartridges input 2 had the same as what's show in the screenshot 1.
I sent both inputs to the cartridge hub and opened it at the same time. Input 2's hub showed up with four normal cartridge slots and the fourth unused (kinda like screenshot 2 but with axes), I put stomp as first cartridge and brute force as last. After leaving the cartridge hub my first input had taken the skins and the cartridges of the second input, but without the action cartridge (see screeshot 1).
I could not reproduce this afterwards
