Hi,
it's likely because on the other side of the network, you haven't synchronized the switch.
I would suggest not trying to enabled disable such system, but instead simply load them from resources, then it will be a lot cleaner, else, you will need to maintain consistency across your network so that your player representation is rigth ( if the user selects female, you need to also affect the instances running across the server on other machines).
Bye,
Jean
