Since Customer Support Agent Caterpepi has closed my thread (i.e. my BUG report), I’ll try to reply here as he suggested (!).
First, I’m quite shocked to read about this (somehow cold-acting) comment from the devs that StarEdit got a headshot just like that. 
But, that’s another story…
Now, what we really like to know is how you developers will handle this reported bug (Load Next Level Trigger Doesn’t Work Anymore), because all of YOUR campaigns (Precursor Campaign; Enslavers - Schezars Scavengers; Enslavers - Dark Venegance) are affected by this (newly created) bug, too. Only to say “we will not support StarEdit anymore” is simply not enough kind of statement.
No editor is able to handle this bug, because it is mainly an ingame problem. So could you please answer in a clean and straight manner if you developers aware of this particular issue and how are your overall future plans look to fill this gap that StarEdit has left.
Thank you in advance!
