So I was looking through the Surgeon and just happened to notice that the math doesn't add up.  If buccs cost 5 rubies to revive then 20 of them should be 100 rubies.  Yet when 20 are selected the cost is 105 rubies.  Makes me wonder how many times I was ripped off before I noticed.  The following is a screenshot to show 20 buccs for 105 rubies.   http://prntscr.com/apvaqo    EDIT:  Ok, just noticed it is based off the original price.  So when multiple units are selected the original price is multiplied then the 50% is taken off that total.  At first look now it seems that it may be better to revive some units 1 at a time, this will take some further looking into.

Good eye!

You are right about the calculation. it's based on the original price.
