Auto Apply Science Overflow
This mod allows you to complete multiple technologies in the same turn.
In the original game, you may only complete one technology in a single turn, even if your science per turn is way more greater than the research cost.
With this mod, the overflow science is immediately applied to the technology you switched to, if there is enough overflow to complete that technology. Excess science is still kept as overflow science, so you may complete even more technologies in the same turn.
There is a bug in the original game that I cannot fix: when you complete a technology using science given by Great Scientist (like Margaret Mead) or science from similar effects, the original overflow science will be cleaned up. Be careful with this.
This mod requires Tech Civic Progress Plus, which computes the overflow science.
