Hi! 
I'd like to start off in my first post ever here by stating that I absolutely LOVE this game! It is fun, extremely stable, and so easily moddable....unless you're stupid like me 
Alright so to my question... Is it not possible to increase the max level of capital ships? Let me explain what I've done so far to get this right, and then maybe someone could tell me A.) it's not possible or B.) I've not modded other files that I need to (if this one, please tell me which ones to edit).
Alright so here's what I've done in order since getting the game.
1.) Downloaded the latest game update.
2.) Downloaded, enabled, and played many times with Solar Sins 2.0 for V1.1 (great mod btw, Thank you to the creators)
3.) Changed the "final level" of each research subject for all 3 races to go to x10 higher; also, changed the final rank for max ships and max capships to go to 17 levels each ending with 90% upkeep but tons of ships.
Ok, all of these worked just fine the first try (except the fleet edits which made the "next command", "Current command", etc labels show "0" once I'd completed phase 7 research; however, I got it figured out and it now shows correctly) So I finally wanted to add 10 more levels to the Capital ships since I was finding that they got to 10 really fast and then were done (I like the thought of them getting a bit more powerful through battles) So here's what I did to do this (it hasn't worked though)
1.) Edited the Gameplay.constants file by adding 10 more levels after "ExperienceLevelData:9" named ..:10 - 19, and the 3 detail lines under all 10 (40 new lines total)
2.) I changed every "ability.entity" and "buff.entity" file for every special ability for every capital ship (except the single level ones) to allow for a max of 8 levels each (this would allow a player to have only 2 at max level instead of 3... this would promote diversification)
3.) Tried to load up the game and CRASH!
4.) Loaded up the Developer.exe, and slowly introduced one modded file at a time, and here are the results:
adding the extra lines for additional levels to ability files made it throw a bunch of errors, but not crash (I also could then click 8 times on that ability, but it gave me random results instead of what I'd put in the file)
adding the extra level info to Buff files makes it crash
adding the extra lines to the Gameplay file does not crash, but it does throw a bunch of errors, and does not let me progress beyond 10th level.
Any help would be appreciated, Thanks in advance!
