Summary

Research & Technology

This hotfix addresses a critical balance issue introduced in the 1.17.4 update. A bug allowed research bonuses to remain active indefinitely instead of being consumed upon use, leading to unintended and massive stacking of research speed modifiers. This update restores the intended behavior, ensuring bonuses are correctly claimed and removed once applied to a project.
