Logging admins actions

I’ve made a site for someone and there’s currently 5 admins active (I have no further involvement with that site then just that I made it), they contact me frequently because something isn’t working anymore like it should be because obviously one of them changed something again…

It costs me literary days to solve those problems (if I even find it) and I don’t want that anymore.

So here’s my question: is there a plugin which logs the admins actions, what changes they made, when, who and so on?
