Board Game Arena

In this tournament, a lot of games in a few rounds are draws:

But draws in Tash-Kalar are very very rare (as there are 2 tiebreakers), and when I tried to replay the games I got a weird notice: "Game abandoned:
Game has been closed automatically due to a technical error (synchro_error_corrupted)". What's going on?
