Thank you for this awesome mod! I thought a lot of this stuff was base game until the fleets became too large to contend with and I started looking into what wemt wrong. I changed that "DMDifficultyGrowth" to 0, but the fleets are still twice as big as the text descriptor says they will be.
I'm not sure what you mean? Do you have a screenshot?
Sadly, I do not. I tweaked dmdifficulty growth along with anything else that looked relevant in any mod that affected combat and eventually deleted/updated magic lib, (which I read somewhere had something to do with fleet generation). I also installed the FleetsizebyDP mod to keep my own point totals from getting crazy. After that, the problem went away entirely.
Here is what my problem was:
The enemy fleets kept getting bigger, so to compensate I'd go past the 30 ship limit and just pile on stuff since burn rate isn't important for this. Figure I had around 38 ships and 1000ish points. The station commander would tell me I'd be facing "at least 2 fleets with 50 ships with a combined strength of 1400ish points. For comparison your fleet has 1000ish points and our battle station has 180 points." Those numbers are from memory and might be junky.
When the enemy fleets arrived, the bigger fleet was usually double the estimated point amount and double the number of ships (not counting fighters). I had the same exact problem with bounty missions - the actual fleet was usually twice as big as the estimate given in the mission text. It was ludicrous!
At first I documented what I was doing. Then I just started flailing.
I suspect updating magiclib was the solution, but with all the other changes, I have no evidence for that.
As an aside, I also had a lot of memory leak problems. Those disappeared as well. Same save file.
But everything is working fine now, bounties and station defense are reasonable again.
