No resource entities will decrease below the minimum yield.
Resource entities generated with less than the minimum (or more than the maximum) are corrected.
Restart is required to change the minimum yield.
To replicate similar mods that don't use yield mode (instead, they regularly replenish resource entities), set both minimum and maximum to 1.0, and enable the yield limit. This will result in all patches yielding 100% forever.
Since 2.0.0, min/max yield settings range from 0.01 to 1.0. If you are migrating from 1.x.x, you may want to reset to the new defaults.
