First thanks for the convenient mod with the configuration options.
But for some reason even after updating the mod to version 1.0.11 I keep getting a small slowdown when the refill is taking place.
You can disable the refill for ores safely, they also refill when it depletes entirely. Oil depends if you're ok with the rate going lower. Some UPS decrease is still expected on 1.0.11 for large maps when using periodic refill
