Description:  When building a seowon district tile, all tiles in that city that produce science increases.  This includes exploitation tiles (that I wouldn't have thought to count as district tiles) such as the the coastal tiles that produce science due to being Joseon.  Now my coastal tiles have an added 12 science on them due to multiple seowons being built in that city, as well as other science producing tiles that I am exploiting.  My science has now skyrocketed due to exploiting this.

Steps to reproduce: Exploit science tiles: Build seowon in city.

Reproducibility:  I haven't tried this in another game but all my cities benefit from this.

Expected Behaviour:  There should be no extra bonuses on science tiles that are being exploited.

Notes:  I could be wrong with these tiles being counted as district, but the descriptions make it sound like these don't count as district tiles.
