Hello elemenpyunome.
This seems to be related to DayZ Expansion mod. In such case there is nothing we can do, the DayZ expansion creators will have to fix this on their end.

expansion's line for that is

	override void OnCEUpdate()
	{
		super.OnCEUpdate();

This has nothing to do with Expansion. The failure in this case happens in vanilla Liquid::GetBoilThreshold, and the reason is that another mod's item has an invalid varLiquidTypeInit value (i.e. a value with no matching entry in CfgLiquidDefinitions). There's no NULL check in the vanilla Liquid methods, which then leads to the failure.
