Set variables to nullptr after they are deleted
While updating some LPC logic a developer noticed a bug where
an errlog handle wasnt getting set to nullptr after it was deleted
this caused a confusing bug that took awhile to track. I noticed
that this bug was all over our code so this commit fixes a lot of
cases where variables get deleted but not set to nullptr
