Yesterday for some reason my fenrir stoped to eat food when i was mounted, when food bar went down to 50% i could not unmount.
I double checked the food amount before mounting so it had 200 food at the inventory, I restarted the game and when i reloged and resumoned the bar was at 45% and i still had 200 food.
I think the food needs to be in your inventory while you are mounted...atleast it was like that before Epilogue (everything in pet inventory returned to your invenroty when you mounted it)
no you don't, when you mount the pet, everything that was in its inventory gets in yours automatically.
another solution would be to not give him ALL the food whne not mounted, and leave at least 1 bag of food in your inv. like this when you mount it you will be able to keep food on your task bar.
