I acquired my shiny charm it came up much like the mega ring prompt and I turned it on and left it on for the duration of the time on the server. I get off and return later and when i open my inventory the shiny charm is disabled and I cannot click on it to reenable it. The only way I have found to be able to reactivate the shiny charm is through removing the charm first with /shinycharm remove then readding it with the /shinycharm command. I don't know if this is a visual bug where it shows that I don't have the shiny charm but it is still active as i left it active when i logged off or if it there is an issue where the shiny charm gets removed upon leaving and rejoining the server. I have tried this process multiple times with the same results each time.

Thanks for the report. I was able to confirm this, and have passed it along to internal. Keep an eye on the ticket status to see what's up.

This has now been fixed for the upcoming version! Closing.
