Title pretty much sums it up. Not sure what else to add because there is literally nothing else to add (nothing in the log file for the mod).

Factorio v1.1.39

Edit: Mod does work but the settings do not, nor does it show up in the mods list. Manually adding it to the mod-list.json file, however, allows it to work although the settings do not show up and the settings file needs to be manually extracted, edited and then, added back to the mod archive.

thanks for the report but I could not repro this behavior.

I can see the mod working just fine as it is.
- I used vanilla 1.1.39 and added mod: worked fine
- I set the percentage to 150 (was 70 by default). game restarted automatically and I checked settings, it was 150 as it remembered.
- started a new game and found this: https://imgur.com/u7LAYYS

it seems to be working with above. of course not a valid case for your setup perhaps.

I checked the settings stuff for the mod and realized setting names are default/old mod name ("minime", which should be "minime_temp"). I shall rename them and put an update to mod portal. I hope it shall fix your problem.

regards

edit: are you using steam or win client from factorio website? do you see nothing on the mod settings when you install mod for the first time, nothing related with this mod? it is strange that it works on my machine then. maybe you had old mod and it recognizes old settings which messes up? can you try removing old mod if you had it?
