I am comparing some shipping costs from our old store to the new one I am working on. I ran into a different between the stores, and thought that changing the max package weight would fix the issue.

Changing the max package weight from 100lbs to 40lbs changed my shipping cost for 3 36lb packages (~100lbs) from $80 to new york, to almost $1100! I am thinking this is not right? Even changing from 1 to 3 packages shouldn't cause this much variance.

...or am I missing something? I have confirmed both ship to destinations are the same, same product, same weight (yes I used ounces when importing products, but lbs when setting the max package weight)

Let me know if you need more information. Using cart 4.24

UPDATE**

Changing my max package weight from 40lbs back to 100lbs didn't fix the issue either, now I'm seeing anywhere from $2000 to $10000 shipping charges

See attached image. I have max package weight set at 100lbs (even though I don't need a max package weight, but I read in another post that this was required to fix the UPS shipping memory leak.

Someone I think the shipping is off a little bit. For small orders, the shipping module works fine, but for larger orders, like the one I posted, shipping get's thrown way off.

Weight of the product is 176oz. The weight I had entered in the 'Max Package Weight' field was 40lbs, then I changed to 100lbs, then 150lbs, just to see if that made a difference.

Is there a hotfix available or do I have to completely reinstall? If it's not too much trouble, and it's easy to explain what to change, I have no problem doing a little work on my end to avoid a complete reinstall.
