[1.2.2723] New caravan auto-load feature causes lag

[Mr_Fission]

Hello, I'd like to report what I think is a bug.  The new feature in v1.2 that auto-loads food and medication into your caravan is causing a tremendous amount of lag in the caravan loading screen for me.  With each pawn, animal, or item I add to the caravan while the new auto-load feature is active, the amount of lag between each frame increases, to the point where it becomes nearly impossible to add new things.  Disabling the auto-load feature immediately solves the problem.  However, this means that I have to disable it as a first step every time I create a caravan.

Although this lag has occurred with every caravan I've formed since the v1.2 update, for specificity, my caravan size was 23 colonists and roughly as many animals (donkeys / elephants).  It still occurs for me even at smaller caravan sizes though.

If I had the option to disable this feature by default, not only would the lag go away, but I also wouldn't have to manually disable the feature for every caravan I make, so it'd be a double win.

Incidentally, if the food and medicine auto-load calculation only occurred one time, right before launching the caravan, it wouldn't have to recalculate each time a new thing was added - which is the reason for the lag.

Do you have a save of this happening?  How long in to the game are you with how much population?  Do you have many mods activated?  Thanks!
