Less arsonist spellcaster when spellcasting as social group activity

Hi, I just want to feedback one thing, I thought was a bug at first. My spellcaster who is in a dynasty (Royalty & Legacy EP) autonomously uses the spells inferniate and copypasto a bit too much. The cause is the "Mysterious" Ideal of his dynasty which includes 'Cast Spells'. Searching in these forums this seems to have happened to other players but with Clubs. 

When the spellcaster uses inferniate it happens almost equally from 0 to 2 times each day. Targets are often empty dishes on the dining table. He does this while painting at an easle in a different room and on a different floor.

Sometimes he uses copypasto on the empty dishes instead. I notice this when I get a pop-up out of nowhere that a copied item has been moved to the household inventory. There, I'd find those empty dishes. I wish he had better taste for valuable objects to copy. At other times, the plates just keep increasing on the dining table which is noticeable with a household of only two sims.

I think it's fun for sims to use spells autonomously, but this happens way too often. My sims deserve clean tables and a life a bit further from death by fire.

Thanks for taking your time reading this. Bye. : )
