Article about disableSerialization

[dedmen]

disableSerialization disables in in the entire VM Context. Meaning all caller's and callee's also get their serialization disabled. So be careful about what scripts your script calls.

scriptVM's that have serialization disabled are not saved at all to the savefile. Meaning they won't run after load.
The Game will crash if it attempts to save a script with Serialization disabled.

Doesn't really sound worth a full ITE post though.
