Staff Question: Is there a character max on Game.ini?

[Slydog 3]

Is there a character maximum or line maximum for the Game.ini file? 

I asked because I am wondering if I have reached the max. I am copying code and pasting it into the Game.ini file window and after I save and then reopen in, the code I added is no longer there. Note: I have successfully added several several lines of code. Everything from Engram unlocks to Harvest modifiers successfully. Now I am trying to add Loot Drops. All the code (including the successful code as well) has been mostly done by and outside program and copied and pasted into the ini and worked until now. Hence why I think I may have found some max limit or something.

 

PS: I didn't create a ticket yet because I figured this would be good information for everyone to know if there is a max character or line set for the file.
