About My Untradeable White Horse

About 1.5 year ago i was just breeding some horses when i ended with my dungeon chestnut (that is untradeable) and a normal chestnut i have just breeded, so i had the idea to try breeding them and the result was a untradeable White horse.

Spoiler: proof

At the time selling it wasnt my plan so i was really happy to finally get one spending about only 30le but now i think im needing some le so i want to know if theres any way i could have a normal White horse in the place of the one i have now
I know the server has the no refund thing as it would be strongly abused but this is not really a refund its more about a Exchange (just like you do with powders in corkus) and the reason why i think it MIGHT be possible is because this is probably a glitch (in my opinion dungeon horses should not even be able to breed)
and if it isnt a glitch there should be at least something to warn you that when you use a dungeon horse to breed the result will be untradeable.
So what do you guys think? Do i have any chances of getting a normal White horse in the place of the one i already have? Is this really a glitch or a intended feature? Any feedback is apreciated. :)

ps- i also heard theres some kind of a glitch that makes you able to trade untradeable items but nah, i dont want more glitches.

 

You could keep it as a collector's item if you want but I'm not sure what the heck you could do with it

 

tbh im kinda doing it already
