I discovered this bug when I tried stack my oak logs from 51 and 13 to 64
One slot of oak logs has a stack value of 51
and the second slot of oak logs has stack value of 13
When I try to combine, it didn't work, like they think they are not the same item
They won't get stack with each other until you drop them on the ground and pick it up
Hope someone will notice this or add as a duplicate
