i am noticing this bug since january.
when imine from rocks , after 2 or 3 hits i get coal. sometimes it says +4 or +3 coal but when i check inventory which had 0 coal before it shows only one. like this i mine 10 coal and only 7/8 appear in my inventory

i am SURE that theres a problem in coal counting of the game and not mine


what do i do

fix this in the new update plz
