Patch fails with "Internal message: The given key was not present in the dictionary."

[FlotterCodername]

Describe the bug Unexpected patching failure of Tyranny's Assembly-CSharp.dll. I don't know why this happens; it's just a public class that I want to patch: public class UIConversationManager : UIHudWindow The issue persists even if I remove all the member modifications:

using Patchwork.Attributes;

namespace TyrannyHighDPI.pw
{
    [ModifiesType]
    public class ModUIConversationManager : UIConversationManager {}
}
