I am using TT10 collars with my alpha and during the course of the hunt I am losing track on some collars. This has happened multiple times with multiple collars. I have to delete and reinstall collar to correct problem. Anyone else having this problem and is there a fix?

When you are on the Map screen, hit the 3 lines at the bottom middle of the screen, select the last option which is Restore Defaults. This should bring your tracks back up without you having too delete the collar and re-adding it.
