any suggestions?

Are you on the staging build?

Hello khan thanks for the response. Yes my test server is on the staging branch

Ah, ya then that would be why, I don't actively push updates for staging builds because the site doesn't allow 2 different version uploads so if i added the new game items it would break it for everyone else. 

This problem will go away on the next update on forcewipe.

Changed Status from Pending to Not a Bug

Changed Fixed In to Next Version
