Ok, thanks for the info. Yeah this sucks, tried to make my mod work without patching but there was nothing good I could jack into in this case. I'm patching a ViewModel, so that shouldn't be such a volatile case. So you can't use a single mod that uses Harmony? Is there a Harmony basic example that you can test? This like you said could be an issue with Harmony and a specific set of system specs.. Wanna minimize the issue :O
