Just logged on after a few days away, to find my tech has gone from 50 to 100 - if it comes from my normal IP address and hasn't been logged onto from somewhere else, is there any chance you could let me know when the last 50 was bought so i can work out what happened (noone was even supposed to be in the building at the time, never mind on my pc)?

You did recieve 50 tech in foreign aid on the 24th, could that be it?
