【Plan】
-Resolve the above issues.

1.Fixed the issue of being unable to construct certain buildings during the exploration period
2.Now all wonders, buildings, and the vast majority of improvements can be built on any Terrains or Biomes.

Next plan: Buildings from previous eras can be constructed.
（ps：There are too many projects that can be built now, and perhaps this function is not needed.）
