I would be curious if other users have the same combination of device and provider who can confirm or deny your query, but from reading the HAZ Tracks thread, it appears that Joe is aware of an issue with the Moto X and the high accuracy setting. (Though this is possibly due only to your own previous comments and not those of other people -- so other reports would probably be helpful)
Quirks ( not a HAZ Tracks issue )
- Nexus w/Jellybean off line maps do not work, consider upgrading to 4.4 or higher
- Moto X not working? try "Device only" rather than "High accuracy"
- Android 4.1.1 map freezes, upgrade your device to 4.1.2 or higher
