DogScepter crashing when code chunk cannot be found for GMS2 games

[Miepee]

This most notably happens for YYC games.
Stack trace is similar to this:

ystem.AggregateException: One or more errors occurred. (Object reference not set to an instance of an object.) (Object reference not set to an instance of an object.) (Object reference not set to an instance of an object.) (Obje
ct reference not set to an instance of an object.) (Object reference not set to an instance of an object.) (Object reference not set to an instance of an object.) (Object reference not set to an instance of an object.) (Object re
