【Error in assignID: recipe-category with name 'electronics' does not exist.

I'll fix this tonight. Thank you for reporting it!

Well I guess we don't remove 'electronics' from the category list or you lose circuits. Can you explain:
1) What version of factorio you are running?
2) What other mods you are running
3) Provide a log file for me to analyze the crash.

I'll remove this "fix" posted in 2.0.4

It seems you have fixed the bug
I'm sorry

I don't know why this error occurs
When I went online today, no errors occurred.

Thanks for the update. Ideally I wouldn't make any fixes until logs are analyzed, because it could be due to some other mod. Keep plugging away and refer to the post I made with links for the log files, and upload if you have further issues. I removed other things the ASM's could do based on this post, until I get more time to test them.
