I think I've found an interface bug; under certain circumstances, indenting multiple tasks makes them either vanish or go somewhere else. I found it with this structure:

PROJECT
Task1
Subtask1
Task2
Task3

I tried to indent (via keyboard shortcut) both Task2 and Task3 at the same time, and they went away.

Possibly important clue: I notice this behavior only happens when the project is serial, rather than parallel.

If there's an official bug-report form thingy, I'll be happy to file this.
