This is the 2th time it hapens btw, the thing is this I train 20 heavy units and just 18 appear in the training window but I still pay the 20 units :S

Please fix this

It isnt becasue of a bug
and u dont actually pay for 20
such things happen in the cases of over head
u click and u will see u are able to build 20 but u end of with less as the over head count changes ure cost increase so
it seems u payed for 20 but u payed a bit more and got 18
for example
u had 30 units of heavy in base
u trained 20 but u are able to build only 18 as the over head increases and ure current metal isnt enough to build 20
hope u understand
