Description

Objects' sleep states are not being properly replicated to the client. While it cant seem to be reliably triggered, occasionally the client will receive a constant stream of sleep events, until the object is awoken again. It is also possible for the client to become permanently awoken and is never put back asleep, regardless of interaction on either the client or server side.

Result: Occasionally, the client will receive a constant stream of sleep events, until the object is awoken again.
