Server crashes when collecting garbage

[EliotVU]

Servers running MutBestTimes are experiencing random crashes when the server is collecting garbage especially during a server travel.

This happens regardless of whether new ghosts or records were set.

The following is a crash when after the server saved new ghost data files:

Socket shut down
Collecting garbage
Signal: SIGSEGV [segmentation fault]
Aborting.

The next log occurs when no new ghost data files are made:
Collecting garbage
Purging garbage
Signal: SIGSEGV [segmentation fault]
Aborting.

Regardless it is not evident whether this is an issue related to MutBestTimes.

Another crash case (only since the last GhostManager related update):

Collecting garbage
Purging garbage
Unhashed name 'BTGhost_STR-JaNyShiT-01-Industry_e9a915bde9c6ccd6ff26fc3a97fd42'
Executing UObject::StaticShutdownAfterError
Unhashed name 'BTGhost_STR-JaNyShiT-01-Industry_e9a915bde9c6ccd6ff26fc3a97fd42'



History: 

Exiting due to error

And yet another case:

*** ServerTraveling ***
Moving '../Saves/Save.tmp' to '../Saves/BTGhost_GTR-GeometricAbsolution_2e216ede3cf7a275764b04b5ccdd005d.uvx'
Save=23.167877

...
Collecting garbage
Purging garbage
Unhashed name 'BTGhost_GTR-GeometricAbsolution_2e216ede3cf7a275764b04b5ccdd005'
Executing UObject::StaticShutdownAfterError
Unhashed name 'BTGhost_GTR-GeometricAbsolution_2e216ede3cf7a275764b04b5ccdd005'

What's interesting here is that the latter is missing a d after 005.
