Guild Wars 2

There are several bugs with guild bounty.
1) we couldn’t start fighting Devious Teesa (just didn’t turn hostile) – it took about 5mins of waiting until we could activate her (yes, I am a guild officer)
2) Yanonka the Rat Wrangler doesn’t stay in one place – meaning we had her move across the map three times in a row, then she failed (timer ran out). Perhaps when another guild finds the right suspicious rat, she moves.
3) Felix shortfuse did not give us credit when we killed him (well within time limit of both bounty, and the event)
Server – Desolation

Same bug with Yanonka and my guild yesterday.
We found the rats, killed them, Yanonka appeared, every members were coming into the fight. Then she disappeared.

Another member found her at the other side of the map but it was too late.

Something is wrong with this boss.
