Clearing bases does actually reduce the ODI.
The current issue is that the ODI level is displayed as a percentage, but internally it’s a much larger number. Let’s say 0-10,000 as an example.
Clearing a base reduces the ODI, but sometimes not by enough for it to be visible as a whole percent on the ODI meter. So while you may not see the meter going down, you’re certainly reducing it and slowing the progress.
We are looking at changing this to make it more transparent, along with rebalancing the ODI reduction from clearing bases.
