True it does not make sense but It also doesn’t make sense you can fit fuel pump in your backpack.I was thinking building materials would be stack-able for convenience sake, with the new addition of the weight system I think stacking items like this could make work.
My idea comes from Sectionalized Clothing - w/ Concept Art where clothes wouldn’t have the space to carry long things like rifles and for the matter at hand not many logs. Where a backpack would be the place to store these things. Nelson liked this idea and commented on it which doesn’t mean it will word for word what the post said but he likes the idea.
If something like this would be the case collecting logs would be even more tedious from 3.0 and I think Nelson wants to move away from a tedious crafting/building/collecting system and the stack-able items like crafting materials could aid in this.
Like the post suggested, clothes wouldn’t have the space to carry things like logs or maybe 1 or 2. So going from that stacking could work. Also logs don’t have to be 2x1 in the inventory but could be something like 4x1 and really it would only fit in the backpack, but stack-able under weight.
