Playtest crash fixes (#265)

* Fix BIUM getting hack time in nanoseconds instead of milliseconds

* Remove blocking call to calculate remaining hack time on CC

* Fix HackClearActor crash when trying to schedule next check when no hacked objects are left

* Potential fix for client disconnect when looting a corpse that gets removed
