Keep getting this ingame bug and been waiting on a petition for over a week now,
I have tried relogging
Zoning
Checking every bp including bank
Opening overflow window
Casting a lower level pet
Any help? Can someone log ingame and sort this for me

Do you have any bags that looks like they have 1 spot open? Could it be an invisible icon possibly? 
Try filling the bags up one by one and look if one acts like full while there’s one spot open.
You can also drag a corner to show all possible slots and those annoying invisible ones too.
