I starting with "Locate Auriel's Bow" Serana does NOT follow me as she should.

I have to use the [moveto player] cheat to get here near me.

I am now doing "Fill the Initiate's Ewer" quest.

When I speak to Serana there is NO "Follow me" option.

Is there a cheat to reinitialize Serana's follow mode (emulate choosing the "Follow me" option)
