I tested the fling trainer and its works for me, so you can bypass the worst situations. I saw a fleetpoint releated post in steam and they say the points are now deep in the code almost unable to edit, same goes for the savegame editor, but cant you hack the shippoints itself, so every ship costs only 1 point?
Edit:
If you use CheatEngine ( normal search) and buy a new ship, u can set the fleetsize to 1 and build a real armada.
So you can split your forces more to burn the damn invaders.
You can have up to 2000-3000 pts fleets in a single fleet, instead of 3 fleets a 1000 pts.
I recommend 3000 for each fleet, sometimes the game crashes for me, if i had more pts.
Btw: u can freeze /unfreeze the values ( 4 ) for every new ship you buy.
