## About The Pull Request
Currently, if dreamluau is absent (which it might be on linux instances
that don't automatically download it), every `call_ext` call runtimes,
crashing the calling proc. This fixes that by using a flag that skips
calling `call_ext` if unset.
## Why It's Good For The Game
Apparently this could really bork the garbage collection subsystem, so
fixing it is a really good idea.
## Changelog
Does this even count as a player-facing change?
