At a fabricator, if you first use trojan(prioritize), build something, then build something again, the second time the delay is initially shown as half the time as it should, then it resets to the full time on the next turn.
Actually, this Trojan is more broken than that--it only works on builds currently in progress, rather than the current and all future builds. So technically it'll even fail to help if you install it before the first build :P
I forgot to apply the effect to new builds, instead showing the correct number only in the hacking results.
Thanks, will fix now.
