1st and 10

The ball is at the 43.5 yardline. 10 yards forward would be the 33.5 yardline.
2nd and 10

Confirmation of the LOS after the incomplete pass being the 43.5 yardline.
3rd and 4

The official spots the ball at the 34 and immediately calls for the chains to move, giving ISU a first down.
But the Line to Gain was the 33.5, so he spotted the ball short, and then gave a first down anyway without even checking where a first down would be.
The same official is even the one who spotted the ball at the 43.5 the previous set of downs.

I can understand some penalties being missed or some weird subjective calls, but this just feels like it was *objectively* officiated incorrectly.
This seem weird to anyone else? (Once again, not just trying to whine about officiating, but this feels like something that is just plain wrong.)
