Dire Boar disappeared !

[Liloze]

Just let me start by saying I am not complaining it disappeared lol

Before the Summer Caravan started I had a Dire Boar parked near my Amphitheatre.
I kept it there through the whole time, enabling me to collect without interference lol
Yesterday I force closed my game ( I always do when I am finished ) came back after one hour to find the Boar had disappeared !
Just for more information, it is my first time I did park a beast, usually I **** it directly if energy is available.
I have read somewhere in the forum that many park these beasts for a month!
How could mine possibly disappear if I did not **** it?
My Question is, does the beast disappear after a certain time has elapsed ( i.e. a week or more) or is this a new fine-tuning or adjusting the game implimented by TL?
Thanks for any information provided.

A Beast will remain in your Kingdom if you do not **** it. You may have experienced a sync error and lost the Beast from your Kingdom. There is no time limit on how long it will take for Beasts to disappear from your Kingdom.

If your beast is outside of the kingdom limits it will disappear when you force close your game. This is so that people aren't stuck with beasts they can't fight.

Thank you both Pika Squirrel and Maguar.
Since the beast was inside, almost in the middle, and not on the kingdom limit,
I think it is a highly likely synch error.
Thanks again for the info and responses
