Hello guys, just now i want to gift a game to a friend, but the problem is, i keep received an error ''an unexpected error has occurred. your purchase has not been completed. please wait a few minutes and try again. if you encounter this error repeatedly, please contact steam support.'', but when i test gifting other game to my other friend, it worked, is there any problem with this? + I buy the game using steam wallet and gifting through steam friends and we're both in the same Region (currency)
