ive bought these enhancements on numerous occasions as well as been given these when ive bought drachmas.

i thought it was strange that when i used these enhancers that the percentage that i am supposed to get isnt what i actually get.

i bought and used the 20% enhancement on offensive and defensive troops and the enhancement did not come to 20%.. 

i checked specifically today to make sure i was right and 20% of 36mill isnt 3mill it should be 7.2mill if my maths is correct..

i use plarium.com and i play sparta war of empires.. 

the way i found out was.. i highlighted the amount of troops i was going to send then i used the enhancers.. the amount of offense did not rise by the 20% that i expected it too.. i didnt check the defensive one due to not being an important percentage as i was attacking and not defending.. if this is a bug then this has serious ramifications as i have used these enhancers for a very long time.
