Fixed by Shoghi on an earlier commit that fixed sending single changed entity data values
Resolved previously.
This was fixed in the Beta 6 build.
No additional damage is taken when the user reconnects, though it does flash like damage is occurring.
Cannot reproduce this. Ate flesh, died while sickness effect active, respawned, and sickness effect no longer active.
I believe this bug is realms only. from 1.2.6.
