A few patches back, there was a similar problem and she came back again. BIS, stop walking in a circle!

Further to this, I noticed a similar problem with weights of items being similar, but having drastic differences to the amount of stamina they reduce when added to ones inventory. For instance I was wearing a field jacket that weighed (with contents) "about 7kg", it reduced my stamina far more than an assault vest w/buttpack that weighed "about 13kg". Also, I noticed that an empty hunting backpack that weighed "about 1kg" drastically reduced my characters stamina (by well over a 3rd) when I put it on (I will create a separate task for this issue). Lastly, my character on Experimental is carrying approx. 35kg of stuff with only 5% stamina left, my character on 1.07 carrying approx. 36kg has about 50% of their stamina left.

Before the patch change on today (10 June), the patrol jacket weight/stamina loss was what usually see. The new version is when I noticed such a large loss of stamina.

It seems backpacks are effected as well. I switched from a big Field back pack to a smaller combat backpack and there was no difference in stamina.

Weight seems to be an issue now - my main character has zero stamina today after 60% yesterday. I also have a second account and on a new character am down to 20% stamina with just a backpack and a couple of items.

Yeah I’ve just logged in. Nothing on apart from combat backpack with 2 fat, 4 cooked fish and some small items and it removes approx 75% of stamina.

Seems still to be an issue in the released 1.08

Can confirm, from 50% stamina (carrying 3 guns) and I stopped to fill up my water supply. This added 1 canteen and 2 water bottles full of water (approx 1kg each) my stamina went to minimum. That’s heavy water!

The recursive weight calculation doesn't seem to work as intended. Fixable by modding:

modded class ItemBase
{
	override void UpdateWeight( WeightUpdateType updateType = WeightUpdateType.FULL, float weightAdjustment = 0 )
	{
		super.UpdateWeight( WeightUpdateType.FULL );
	}
}

modded class PlayerBase
{
	override void UpdateWeight( WeightUpdateType updateType = WeightUpdateType.FULL, float weightAdjustment = 0 )
	{
		EntityAI attachment;

		int attcount = this.GetInventory().AttachmentCount();
		
		for (int att = 0; att < attcount; att++)
		{
			attachment = GetInventory().GetAttachmentFromIndex(att);
			if( attachment )
			{
				attachment.UpdateWeight( WeightUpdateType.FULL );
			}
		}

		super.UpdateWeight( WeightUpdateType.FULL );
	}
}
