I'm having trouble getting these (this one and the misc robots+++) mods working. It stopped working in a16 and still doesn't work ( they have all been updated to a17). I've removed all other mods except this and the misc core one you need, including the misc robots +++. This is a link to my log https://gist.github.com/7ac7c0f5e6cf42744a7f62ea8ed48ab1 . It is the curve part that is red. I know next to nothing about mods or how they work. In my last game, where i noticed the issue, I built a few cleaner and hualer bots then when i went to build an er bot it would simply dissapear after being constructed. You would see the yellow progress bar finish then nothing would happen. I tried spawning some in the dev mode but that wouldn't work and it produced this error. Here is the log text :
