After upgrading a world from v3.3.1 to v4.0.4, I checked everything. Whenever an SRD actor had some problems, I checked the actor in the compendium, and whenever they also had the errors, I write what I did, so here it is. It may not be the "proper" way to implement the features / activities, but at least it points out the monsters I found that had problems. I'm sorry I don't know how to contribute, otherwise I would have implemented all of this myself.
