Do you know if this will merely restore her on the beach, or set the state so that she's preserved as 'normal' fr the rest of the game? (As I understand it, she's also supposed to work as a crew member, but doesn't for anyone?)
This command sets her variable to what it should be when you import a save having kept her. Everything should behave exactly the same from that point forward. Also, since you're only altering this one very specific variable, it shouldn't mess with anything else in the game. That being said, it is a debug command, so there is still the risk of something going wrong somewhere unfortunately.
Also I thought this was the case but I just confirmed with our design team; Vela is not intended to be a member of your crew. They didn't want her getting injuries and possibly dying during ship combats. The intended design behind the little orlan is that she hangs out inside of your ship and can be talked to, and can have banters with all the companions.
Hopefully that helps, even if it's not necessarily the answer everyone wanted =(
Ah, that makes sense then, I figured she was just bugged since I couldn't have any conversations with her haha. Do you know if there are any actual conversations you can have with her besides the one on the beach with Engrem and the ones she has automatically with companions? If I talk to her I just seem to get generic sailor dialogue (i.e. "Where to next Captain?")
