And that's a good warning. While changing variables might not crash the game it will surely trash your save if you don't know what you're doing.
As for easter eggs. I know just one. While it isn't somewhat great as exploding deer, it is surely unusual. On the field map, somewheare on the line of trees near the passage to eastern darkwood is bee hive. If you interact with MC will aim for it and shot it after which there's a dialogue about currently this not doing anythig.
A warning with sin
It is a fun and simple way to say “Hey stop messing the variables, it may not be a great idea”
The beehive was supposed to be used for the candles (the wax), but then he decided to go medieval historically accurate and chose to use the fat of animals.
For now it remains there, standing, it could be used for a wedding cake the honey… for the next marriage.
Ah... Necrophilia. I knew MC is such a horndog even dead are not save from his lust.
I should use photoshop to create a curse meme I know, just wait and see getting me banned
