Making a Stealth Explorer Ship for prolonged operations, so I'm using a commercial engine for fuel efficiency, but gave it a military jump drive for space efficiency (see below for ship design).
Except now it can't jump on its own. Says there isn't a jump drive capable of allowing commercial engines to jump. I've double-checked, and yes, the jump engines do have enough space capacity for the ship's size.
I thought that it used to be that military jump drives could have any and all ships of the appropriate size to jump, even if it had commercial angines. So, to ask: Did something change? Am I remembering things wrong?
The ship in question for reference, in case I'm just missing something obvious:
