No errors in DCS.log for SLMOD. It appears to be stats for one 14 pilot that is missing. It did record his total flight time, but none of his weapon stats are there. He did have a rio. I verified against Tacview that the 2 other pilots, one with a rio the other without, did have their weapon stats tracked correctly. Below is the pilot with missing weapon stats. According to Tacview he dropped 3 bombs (non-hits) and one air-to-air kill with AIM-54A.
