Can’t reply to bugs there so will do so here:
It’s possible that the Prestige does nerf the Chronomancy upgrade intentionally - then the bug is about documentation/description rather than actual behaviour. However, if it’s intentional - since it only happens for her P3, then it’s a pretty worthless Prestige. I’ve tried it on PTR as well as the live version; in its current state, it’s a hard no for me. It’s not just the TS every 4 mins becoming 5 mins - it’s that you need to skip some TS’es (like the one at 10:00) as save it for 12:00 or 13:00 min, then delays the next TS to 18… but if it’s a mission where you’ve got a big base to kill at 20-21, then you’ll save the TS for then. Effectively, you’ve gone from 5-6 Time Stops in a typical game to just 3, sometimes 4. Wouldn’t be worth it to anyone, especially since by late game you’ve usually already got a massive army.
