Black Tiger III - Editor/technical help with a rerun [SPOILERS]

[MyP]

Hi, I ran through Black Tiger 3 but at no stage was there a trigger for hostilities. That differs from what I have seen on Youtube. Perhaps it is because I changed the pathing for the ESG, since hostilities start with a (scripted?) mine attack on Youtube. I was also late getting a positive id on all surface ships. Perhaps it is because I am running a CMO build (1.02.114714) from a year ago and a CSP build from the same date. I am not familiar with the editor at all.

If I rerun this scenario to try and play again, what do I need to do differently to trigger hostilities? A few progressive save games are attached.
