Got the following error on our server:
PlayFabError: StatisticNameConflict, message: A statistic with the specified name already exists, details: , httpcode: 400, httperror: BadRequest, user: 1496FF3D832B2544
The only call in the API that returns this error is CreatePlayerStatisticDefinition, and we don't call that. The only statistic calls we make are to update player statistics and get player statistics.
