Thanks man

@Ripper The only way to do that would be to make a new mod. You can change the amount for yourself if you want. Go to:

C:\Program Files (x86)\Steam\steamapps\workshop\content\780290\2636319658\ModdedYML
And open Headquarters with Notepad++ or a similar text editor. Regular Notepad will work but it can mess spacing up sometimes, so try not to change any of that.
Scroll down towards the bottom and inside of brackets you'll see:

[h1]Make sure the brackets stay! They just won't format correctly this comment[/hr1]
CharacterXPTable: 0, 0, 0, 0, 0, 0, 0, 0, 0

Change that to whatever values you want each level of XP to require, so if you want newly acquired characters to start at level 6, change it to:

CharacterXPTable: 0, 0, 0, 0, 0, 0, 345, 420, 500

Or for a quick catch up, you could do something like:

CharacterXPTable: 0, 10, 20, 30, 40, 50, 345, 420, 500

You can change those to any positive integer value as long as they increment for each level.

Pushed an update for newest version that broke this.
