kill X quests not completing?

[harry2]

With the sound animation bugs... i also noticed that I killed 2 beaver and did not get the kill a beaver quest completion.

also raiding a bird nest kept spawnign magpies but the magpies were not hitting me like they normally do when i raid they were just landing nearby

the only way you are not getting the kill credit is if they die from bleeding out

2. make the bird fly away, wait a while and then raid again so it doesnt have enough time to fly back before you finish

Could be a ting where the quest isnt active? I feel like that has happened to me before\
