I suddenly gain a 4th bag in clan map

[sayong]

When i get stones from towers at clan map somtimes i gain an additional bag?
I have a2 pet i should only have 3 bags but when i repeat the procces of putting and getting stones at clan map towers i gain an extra bag but it only have 2-7 space i wonder why?

When you gain this extra space is it when you are building/using up material in your backpack? If so the items that are in your inventory do not seem to leave as they are being used up. Which then may show you have extra space in your bag but it's really replacing what material is being used in building. After you fill these extra spaces leave the storage and check your backpack to see if you still have these extra spaces.
