Probably, trebuchets are assigned to a number of ships in that mission (Black, Grey & Gold wings). And there's this SEXP which I presume means that all hostile ships in the mission will Treb the Einstein when Green wing arrives (ouch)
$Formula: ( when
( has-arrived-delay 0 "Green" )
( good-secondary-time
"Hostile"
100
"Trebuchet"
"Einstein"
)
)
+Name: Use Trebs against Einstein
+Repeat Count: 1
+Interval: 1
That event isn't present in either the original retail release or Blaise Russel's 2005 re-release. Additionally, in those releases, only Grey wing has Trebuchets. So when and why was it rebalanced?
I made these changes, because (at least on medium difficulty) it is all too easy to destroy all bombers without the Einstein even suffering a scratch, but it still gets destroyed because of a "containment failure" due to battle damage. I think the current setting makes it a little more credible. Do you think I went too far?

Good news:
The updated mission worked and I got two escape pods.
Not great news:
I think this is one of those missions that is maybe supposed to be lost because I saved all the convoy craft (except for the Einstein) but in the mission debriefing it said the loss of the convoy ships was disappointing but understandable due to the number of enemy ships. It then said they will try to get MT help.
However, this is better than before due to the fact that the debriefing now talked about how you at least saved some of the scientists and research (on the pods).
Yes, the Einstein is supposed to be destroyed. It always happens. Even if it survives the pirate attacks with 100% hull integrity, it loses containment due to battle damage as soon as 90% of the pirate bombers are destroyed. The debriefing does indeed sound a little strange as it always says that "Without the science vessels, their crews and their research, it seems that we will fall seriously behind in our research into the Nyarlathotep." even if you save the escape pods and therefore did not lose any scientists.
Oh, and sorry about that artemisdh.pof. I oversaw that I had changed the model name. This was necessary because otherwise the game would have used the retail model which really does
not live up to today's standards.

So, yeah, you now need the 2014 mediavps to play Derelict. I changed the opening post accordingly.
