im very new to this game and i wonder. how will we know that save is not compatible? it would not load? strange ingame bugs?
It would crash, I imagine - I removed some procedural generation that happened at the start of a new save and moved it to when the quest starts.

Flourish bug is being fixed by Alex for 0.9.1. For now, you can avoid using ships with modules yourself and use the "nuke" console command once all enemy ships are dead/retreated to end combat.
Ninth Battlegroup aren't really meant to be entirely fair, hence why their ships are intentionally overtuned and their fortresses are guarded by a frankly ridiculous number of large fleets. They're an endgame threat, which is why they almost entirely stick to their systems aside from the occasionally hyperspace patrol.
As for rewards, they've got pristine nanoforges and fancy ships, so that seems about right.
