I'd like to see Deer spawn in grassland forests.
No need to worry about needing the tile surrounded by other forest tiles or anything; just give it a small chance of spawning in forest, it will naturally be more likely to occur in large connected forests tiles than a single lone forest tile.

This brought sth to my mind. IIRC, in Civ 1 deer could appear in a tile that had no ressource whatsoever when a forest spawned there. So, is it possible to make deer be present in a tile but require a forest to actually bring the yields and make it 'harvestable'?
If so, the problem would be solved as soon as you have a couple of Priests of Leaves running around casting bloom without giving to much of a boost in the very early game.
Just my 2
