Fun mod, thank you!
Small conflict with Opetera's Inventory Sensor mod, occasionally on loading a save the error message below pops up. Disabling either mod allows the save to load. Not every save is effected, so not sure on exact steps to re-produce. Seems to have been introduced after 15.11, all was cool on 15.11. Cross-posted to Inventory Sensor too. So small bug with an easy work around.
