Token issue

I'm having issues with some of my player characters tokens losing connection to their sheets where they can't move them on their own and it wiping out their stats and we have to keep re-assigning them. Not sure if this is a glitch or I'm doing something wrong when I move the group between maps.

It sounds like the tokens may be set up improperly. Take a look here and see if you can see a step you might be skipping. Usually this is caused by someone creating a token, assigning it to a character sheet, making it the default token, and then doing subsequent assignments (like linking HP or setting vision). Any change to the basic token behavior means the token needs to be made the default token for that sheet as the last step. Otherwise dragging the character to the tabletop won't reflect the latest changes.

I'll take a look. I'm sure this is user error on my part. Thanks so much for your help!
