I didn't know where to ask this so I will do it just here.

When canning human meat and using this as ingredient in meals, the meal loses the property of containing human meat. This means that cannibal colonies cannot use canned human meat and get the ideology bonuses.
Vice versa, non cannibal colonies can butcher humans and then can them, after which no colonist has any issues with eating a meal produced with it anymore. I could understand this with making hotdogs since who knows what's in hotdogs, but canned meat...

Is this a intended feature or a thing impossible to avoid the way the mod works?
