It's not loading the correct signals...seems to be loading the same for every ship.
It's also buggy in that when you clear all the signals, then put new ones on and click save, it doesn't always retain that setup permanently. It reverts back to the "default" signals, which shouldn't happen in the first place (every release up until this point, it has retained my saved signals across mod versions).
Might want to check out the save/load signals to confirm.
