So i was correct. It appears it works for them because they used their own
method to get the environment size manually, rather than using a real and exist
Microsoft API to do it. My code on the other hand uses a real ms api, probably
one that wasn't added by you guys, just as I thought. But it will take testing
the value of EnvironmentSize to know that for sure.

environmentLength = (ULONG)(mbi.RegionSize -
        ((ULONG_PTR)environmentRemote - (ULONG_PTR)mbi.BaseAddress));
