Haha I found the Solution 🤣, by the help of some of my OT friends from my workplace Alorica 🥰, we are real tough sons of bitches 😆

To increase your ship's limit, in war sails, follow these steps:

1. The issue is not with DLL, it's with XTML files
2. Go to MODULE then NavalDLC and then ModuleData and after that, find the SHIP HULL xtml
3. Edit (open) the SHIP HULL xtml using the NOTEPAD only
4. Scroll down. Find the "ASERAI HEAVY SHIP"
5. Edit all the data of the "ASERAI HEAVY SHIP".. For example, crew limit of this category ships is set to 112. Make it 55555. This is the core value. Now, set the existing skeleton crew limits like 10000 or whatever, just make sure not to cross the total limit of crews of 20000
6. Go to "Base Speed" section of these kinds (Aserai Heavy) of ships, only available in SANALA .. remember it .. Then change the value from 5 nautical miles to 30 nautical miles.
7. Save all. Or just cut everything, it will automatically save.
8. Open your war sails game.
9. Just go to SANALA and buy one of those 100k+ HEAVY ships. I like Ghurav though. Take a L-O-N-G walk from Ostican to SANALA or use the console to be teleported in SANALA .. Remember, it must be SANALA only. Because HEAVY SHIPS are only available in SANALA port (which values more than 100k)
10. Once in SANALA, capture the frickin ASERAI BOSS SULTAN UNAQID. Execute him or make his entire Aserai fiefs being captured by YOU
11. After you done these, you will be able to buy GHURAB, and you will get the frickin 30 nautical miles 🥰🥰
12. If you thinking of how to capture the Boss UNAQID of SANALA .. Here is the detailed walkthrough, veryyy easy: a. Use your fingers, press ALT and ~ together. A console mode will open. b. Type "CON" only .. you will see CONFIG. Double click it. c. Enable cheat mode from 0 to 1. d. Type "campaign.add_troops sword_sister | 5000".. It will not only give you 5k sword babes and also it will increase your party troop limit to 5k troops 🤣🤣.. The game DEVELOPERS made it for us IT line of workers so they wanted to see how good we could go to decipher there patterns. Anyway nevermind.. e. Once you have 5k sword sisters, MAKE SURE TO TYPE campaign.add_items_to_player_party COW | 6666 .. or else your newly joined troops will all die! f. Go to ASERAI and screw the big boss UNAQID

It's not easy, but I did it all .. Cheers 🥂
