Monkey Madness 1 [Bug?]

I just started Chapter 3 where after you talk with Zooknock and give him the relevant items a cutscene starts and afterwards he gives you Greegree.
Well just as the cutscene started it ended abruptly (without me doing anything) and now I have no Greegree and I am afraid I have to go collect another talisman.

Is this a bug or did I do something wrong?
