you can now drop items. we fixed it.
if you can't drop the item, make sure to verify game files or reinstall the game and launch the game. press play button and play the game for around 1 minute to trigger your drop. because if you keep it in the background, it will not drop.
You drop the items every 60 minutes which is 1 hour, but sometimes you should play between 61-63 minutes to trigger the effect.
Thank you and Enjoy!
