report: I found a planet with stellar reflector array, not sure if because of another mod or if this is vanilla behaviour. After colonizing it, the bonus to food production from the structure only applied to the food commodity and for the farming building (no bonuses when using artisanal/subsidised farm or after switching production to biotics or rectificates). If you play with TASC I think you can also build the arrays, so you may end up with this happening more often. I didn't find other planets with this condition in my next playthroughs so I didn't test it again.
