For some reason this version has lost the variations that I had previously added, where instead of direct oiotoshi, we first take the ko (if we happen to win it, it's more efficient than oiotoshi, and otherwise we just revert back to oiotoshi). For instance: B1A2D1B3C3A4A3. Of course accepting these variations means that the student doesn't necessarily need to see the relevant idea (oiotoshi) allowing the sequence to work anyway independent of ko - but I don't see any other option but to accept. So I added them.
kovarex: Hello, this was probably caused by the big duplicite problems merging, we had 3 different sets with this problem, and each were separated. Now, all the 3 problems were merged into one, which exists in 3 sets at the same time. The bad part is, that one of them had to be arbirtrarily chosen as the main, so sometimes, the less detailed sgf was chosen. The good part is, that from now on, when you edit a problem with known duplicities, you edit all of the occurences at the same time.
Resolved.
