Does anyone have an Idea about THIS?

I seem to be finced in this morning. This is on runway 35R at KPWA OKC, OK.O don't know if this is a bug, or on purpose. Last night I updated X-Plane 10 downloaded about a Megabyte of data, flew a bit and everything was ok. this morining I took off on 17L and noticed something in the middle of the runway of 35R. I circled around did a downwind and there in the middle of the runway although on the threshold was this antenna. So naturally being the inquistive person that I am, I landed to see if it was indeed solid, if it would crash me, or maybe I was seeing things. I wasn't seeing things when I hit it I had a terrible crash, probably non survivable. I kind of laughed and shrugged it off, shut down the computer and went to church. After coming back from church, eating dinner, taking the dog for her daily ride, I fired up X-Plane 10 and found this. Is it a bug, or Austin having a snse of humor? You be the judge.
