Changelog says as of 0.2.1 this mod is compatible with Factorisimmo 3 with solar requirement only 1%. Just added Factorissimo 3 to my existing save with 0.2.3 of this mod and can't place any new towers on Aquilo (existing ones continue working fine), with the item showing 25% solar required for placement. Did not try creating a Factorissimo building and seeing if they could be placed inside. Removed Factorissimo and can place them on Aquilo again.
Item tooltip indicates Maraxis and Vanilla Galore Continued also affect this item, but not sure what the likelihood is of either of those having anything to do with this issue.
