[BUG] Tokens Move Independently

[LonePaladin]

Describe the bug
Tokens move on their own between sessions.

Environment Details
Foundry VTT Version: 0.7.9
Follow Me Version: 1.0.0

To Reproduce
Steps to reproduce the behavior:

1. Set tokens to follow each other, in a chain -- so Token 2 follows Token 1, and Token 3 follows Token 2.
2. Move Token 1 around to start the train going.
3. Exit Foundry for a while.
4. Restart Foundry, launch the world.
5. See that Token 2 has gone off on their own, while Token 3 has not followed them.

Expected behavior
Tokens should stay where they were when you closed the program.

Screenshots
I don't think a screenshot is helpful here.

Additional context
When a token moves around on its own, and another token is set to follow it, the latter token does NOT follow the first.
