I bought the pet Panda from the cash shop today and after clicking to summon it, I told it a command. In doing so, the game crashed and after I relogged I no longer had the pet Panda. I also don't have the NX cash back to use it on something else if pets do not work.
You should post this in character issue for a chance to have your NX refunded. https://royals.ms/forum/forums/character-issues.55/
