Help with assembly edit

I'm doing a simple assembly edit on linux and I'm getting an EAC error that my assembly-csharp.dll file is an unknown version. EAC doesn't run on linux so I'm very confused by this. I have no problems editing 7dtd and unturned assemblies, I do not know why this one is giving me some fuss.

The exact message is: EAC ERROR: CLIENT VIOLATION: UNKNOWN FILE VERSION: HURTWORLD DATA/MANAGED/ASSEMBLY-CSHARP.DLL

any help with this will be greatly appreciated. All I'm editing is one IL code using reflexil

Nobody can shed some light here? Just a nudge in the right direction is all I need...

Why dont u try to edit it on windows instead of this linux?
