If it doesn't smell rancid and it was out for just a night, I suspect it is okay.
I store my bacon grease in an old cereal bowl covered in plastic wrap and stored in the refrigerator. I usually filter the grease with a small strainer lined with cheese cloth. I have added to the same bowl for a year with no deleterious effects. I keep telling myself I will switch to a mason jar but I haven't yet. This is probably not the optimal way to store bacon grease but since I use it a lot to cook with, I like the larger opening of a bowl so I can just use a large wooden spoon to dish up a "chunk" for cooking use.
