I assume you're referring to this error:
Runtime error in agent 2 21 9000 script 2 21 9000 1 unique id 9497
Anim change failed - on part 0 which has base 0
[frat 2 {@}anim [3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 ...
The problem is that your animation string tells it to go all the way to frame 18. But you only have 18 frames, and just like in SpriteBuilder, the game always counts the first frame as 0, the second as 1, and so on.
Essentially, you are telling it to use 19 frames, but it only has 18 to work with. Remove the offending 18 at the end and it will work perfectly.
