To start with I'd like to thank you for maintainig this mod. It's a great quality-of-life improvement and this seems to be the most stable of the several implementations I've seen.
I've noticed recently that when I install or uninstall other mods it gets things into a bad state where this mod doesn't work anymore. When I first encountered the issue I had just installed Helmod but then uninstalling didn't fix it which was confusing. Luckily I noticed weavminas' reply to the other thread suggesting switching the bonus range from 1000 down to 500 and then back up again. That seems to fix it for me every time, so there is an easy workaround. But it is something I'm seeing pretty consistently whenever I install new mods now. I feel like it wasn't always happening so it could be an interaction with another mod. It may have started cropping up for me only after I installed Krastorio but I'm not 100% sure.
