Fix for the “NG Oil Indicator” on the Abilities+ page.
This is an issue that has been fixed in the most recent patch for the game. However, if you are using the old version, you will need to fix it manually.
To fix this issue, you will need to insert an “Oil Effect” into the abilities.xml. This can be done by simply editing the file manually. The easiest way to do this is to use the NMM utility to install the required file.
Once you have done this, you will be able to see the “NG Oil Indicator” on the Abilities+ page.
