Solved. I managed to figure it out. For anyone interested: 1.In the enemy editor, select the enemy you want to remove the ignore evade augment from. 2.On the first page, in the AI Index box, double click into slot 1. This brings up a list of enemy gambits. 3. Look through the rows to search out Null Evade, in the first 'Action Object' column. Then just select none, across the entire row, to remove. So long as there is nothing in the enemy AI to activate the Null Evade augment, it won't activate, and your shields will remain useful.
