Ditto. My sim was burning 1 year old pile, but could not throw away the ashes due to lack of trash can near by. The next day a random sim walked up to the ashes, grabbed it and walked over to a trash can! Sop - there was a trash can there the whole time, wondering why my sim could not use it...
Also - the leaf piles look a bit misplaced in Oasis Springs. I've now played first 3 days of Fall there, and tried to get rid of numerous piles from a year ago. Problem is that even if my sim is able to burn and trash those leaves, the next morning the pile is back. There is no leaf on the ground, and nobody raked anything. Looks a bit weird on green green grass of Oasis Spring... and even stranger in the desert areas.
