I can confirm that this is still an issue. Is there any update on when this might be fixed? I love using this mod to control my Realistic Reactors setup, but my control rod CPU keeps erroring. Below is my code in case it will help you. Forgive the bad note-taking; I'm still polishing the code. If I replace the CPU it seems to fix it for a bit.
