Str 114 Level 40 =154 carrying capacity. I was taking Buckets of Water and was able to pick up 3 which puts my carried weight at 181.
Further testing has revealed that if I am at less than full capacity I can pick up a bucket of water and exceed the carrying capacity. Unable to exceed capacity with any other heavy item, and unable to pick up other items while capacity is exceeded.
It's a very Benign bug that really doesn't have a game altering effect on anything at all. (don't say it!)
