Hi Dan!
Looks funny with all the venison on the ground and starving bannies. :D
The reason is all the tools, coats and hides in these sacks which have a capacity of 150. Normally, venison can be put there but it’s 100 food and cannot be split. Unfortunately they are too stubborn to carry food from the ground right to their home. I tried it when making the goahti to avoid exactly this in the very early game but it ends up in people picking – dropping food at their homes caught in a loop.
The only solution is building a storage shed to make the meat available, as you did.
I will increase this limit for attachments. Thank you for this hint.
