close your server. make sure you have

[/script/shootergame.shootergamemode]
OverrideMaxExperiencePointsPlayer=15532833
OverrideMaxExperiencePointsDino=1522496

(the bit with the brackets is necessary) paste it in at or near the bottom of your GUS, save the file. (not 'save as'. just save) and then relaunch your server. This worked for me in singleplayer. Can't imagine it should be much diff for a hosted. After doing all those things, however, it did clear all the mods out of my active list and reset my custom settings. Just had to put everything else back in order. AND, unfortunately, I am having some issues with dinos stats just resetting them selves to whatever number (almost always lower than what points i had put into the stat before logging off), but I am running this in conjuction with Annunaki, so this issue could be from either mod, or a combination.
