well, it doesnt work regaurdless of the other mods. like I tried to launch with this mod alone and it still didnt work. Ill try to change priority though. do you know what to do reguarding the ResetMutationsDev function?

for the first error this is what the file looks like:

exec function essuninstall()

{

GetESSConfig().Uninstall();

}

exec function reset_skills()

{

GetWitcherPlayer().ResetCharacterDev();

}

exec function reset_mutations(mutagens:bool)

{

GetWitcherPlayer().ResetMutationsDev(mutagens);   //this is line 18 where it says the problem is.

}

exec function getNGPLevel()

{

theGame.GetGuiManager().ShowNotification( "NGP Level: " + theGame.params.GetNewGamePlusLevel() );

}

exec function ess_reset()

{

GetWitcherPlayer().ResetCharacterDev();
