im wondering where you saw "MAXCAPITALSHIPS"? i saw the other one, "MAXSHIPSLOTS" in gameplay.constants, but i dont see the other... can you please tell me? ive tried find and replace with all the text-editable files i could find
Erp, there are a few things wrong with this picture.
First and foremost, maxShipSlots in gameplay.constants should not be there - it's a very very old file version. I believe from patch 1.03 and on, gameplay.constants does not have an entry for maxShipSlots 2300. If you're curious, that was in there for the Vasari research that increases fleet points. Anyway, re-download the mod package from the site's Downloads, and update your game 
Second, the MAXCAPITALSHIPS thing is a research file. The full name is RESEARCHSUBJECT_MAXCAPITALSHIPSxxxxx (where the x's are the race and number, like TECH00-07). There are also RESEARCHSUBJECT_MAXSHIPSLOTSxxxx for each race. Basically, each rank of the fleet point research has one of these file, so that's why they number 0 through 7, for the 8 ranks.
Each of these files adds fleet points to the previous total. The first file (00) sets the starting fleet points to 100, and then adds 150 when researched. All consecutive files just list how much they add.
Hope this helps a bit
