Created Unassigned: Inconsistent virtual method obfuscation state detected. [16]

Hi.

Thank you for Obfuscar 2.0 rc7.

Windows 7 x64 SP1
.NET 3.5 assembly

Configuration file:
```
<?xml version='1.0'?>
<Obfuscator>
<Var name="KeepPublicApi" value="true" />
<Var name="HidePrivateApi" value="true" />
<Var name="KeyFile" value="..\..\..\StrongName.snk" />

<Module file="..\..\..\MyAssembly\bin\Release\MyAssembly.exe" />
</Obfuscator>
```

Output:
```

Done.

The assembly has been merged with ilmerge and it seems that there's a reference to another assembly that has already been obfuscated.

Any ideas?

Thank you.
