I think this was an issue in the past but do not know anything about ALiVE's multispawn as I have not used it in a long time. Could you tell us what exactly the issue is and explain more what's going on.

It was my mistake. I renamed my mission after the first trial, and forgot to move my scripts and stuff to the new folder. :x

The only issue I had there after was probably more of TEI's fault than ALiVe's (It was only spawning the insides of the Pelican and not the whole thing).
