Browsing through summit details in the database I noticed that DJ5AA has activated two summits in YU, on the same date when I also activated those summits. It was very strange, since I recall working him from both summits.
It turned out that there is a mixup with his logs in the database: many of his chaser entries are in this moment listed as activations of the summits he obviously chased. I do not know the extent of this mixup, if DJ5AA is the only station whose logs have been garbled.
