The landscape was very small so I thought that it was the reason and started to run somewhere else.
The damn dragon started to hit everyone on the roads, get lost, fly around randomly, and when it came near me, still didn't land.
It was time to test the bow........ but the aim mouse movement is so slow that I could hit the dragon like 2 times.
I felt so frustrated that I just reloadded, and the dragon didn't appear this time.
What should I do next time?
