Is there something I don't understand?

When the streamer has already collected the drop, the script continues to watch it without paying attention to other drops. And it turns out that the script should watch two other drops, but this one is assembled and the other one is watching

priority=[                                  # Custom priority in this case for example:
    Priority.DROPS,                         # - When we don't have anymore watch streak to catch, wait until all drops are collected over the streamers
     Priority.STREAK,                      # - We want first of all to catch all watch streak from all streamers
    # Priority.ORDER                        # - When we have all of the drops claimed and no watch-streak available, use the order priority (POINTS_ASCENDING, POINTS_DESCEDING)
