Have I punched it or not?!

Polish Champs in sprint distance were in Wroclaw ZOO. Because there were so many people, I felt like on PWT or WC. Probably they didin't know what we were doing there and what it's orienteering. They just came to see the animals.
I was the fastest on this competition (39" better than the winner), BUT:) after the finish I realized that I don't have 13th point! I must have been very tired at that moment of the course - I don't remember I punched it or not. Girl that was looking after the point is sure I punched it. How it was real? I will never know.
