Not sure if this is a bug or just me, so apologies if its me.

On the castel the lock time with no bonus is 12.5 seconds, i have robotics to lvl 5 and accelerated locking to lvl 5 not sure how the stacking works but if i do the seperatly i get 12.5 - 25% = 9.37 seconds for the bot skill then  9.37 - 25% = 7.03 for the accelerated locking skill, but looking at the bots stats when its active my locking time is 8.33 seconds. If i do the bonus as 50% by adding them together i get 12.5 - 50% - 6.25.

So none of the figures i get match what the bot stats say, where have i gone wrong.

Thanks
