Perhaps they resent a poorly communicated request. Perhaps the task giver does this literally ALL THE TIME ... getting other people to do their work. Maybe the adventurer wants you to fail, because you do this all the time, and like, maybe for once you should do it yourself.
There's lots of reasons things don't get done in projects. Mind-reading and coming up with explanations about why someone is failing in the project is a shitty replacement for communicating needs and wants clearly in an organized fashion.
That is, when a project has a project manager, the project fails because of the project manager.
