I couldn't find any bugs regarding this when searching, so sorry if this is duplicated.
How to re-create: When having an effect that's about to end, open and chest and stay in a chest until the effect is supposed to wear out. Instead, it lingers at 0:00. It eventually wears after awhile.
Sadly, while attempting to get a .gif of this in action, it wasn't happening anymore.
Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w42a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time. If you are the owner/reporter of this ticket, you can modify the affected version(s) yourself.
