如图

我花150点pp让我在多研究一段时间？

反向加成

我记得是研究的加速机制变了，所以汉化那块可能稍微出了点问题

研究加成从研究时间减免变成研究速度加成了

研究加成机制变了之前吧友搬得内容看到的，所以原汉化翻译就会出错

Lastly, we made some changes to how research bonuses are granted and how ahead of time bonuses are handled. Regular research bonuses are no longer reducing research cost but instead boosting research speed. A previous 50% reduction in cost is now a 100% boost in speed. Ahead of time bonuses have been changed to apply a flat reduction in years rather than a reduction to the penalty, so a 1944 tech with two years of reduction would be treated as a 1942 tech for the purpose of calculating research time.
大概这么个玩意。。百度翻译一下应该都能懂

显示BUG还是真的就这效果？

刚才又去确认了下，加成还是有的估计是新版机制更改的缘故导致旧汉化出现错误。
