I know theres a topic already about this, but i have tried everything to get it to work, Infact i have it working to an extent, maybe they have patched it out of the game recently.
Basically long story short, i use this for my game.ini https://pastebin.com/qyT0PNcc
When i go in game and tame a dino, for example a level 1. the game will allow me to level 32 times which is of course what its meant to do, i thought this override allows you to level them up more than what the game allows you to, instead the only thing the override does for me is changes the amount of XP required per level. for example level 1 needs 1 xp, then 2 then 3 then so on, is there no way to increase HOW many levels they can gain rather than the what the game has it set to?
