Prometheus should successfully process the file.

To Reproduce
Steps to reproduce the behavior:

• Run lua cli.lua --preset Weak --out mobdebug.out.lua mobdebug.lua
• Observe error in the Vmify step:

PROMETHEUS: Applying Step "Vmify" ...

It seems that PR #205 fixed this issue. I tested it on my system an no longer got "Unresolved Upvalue, this error should not occur!".
