Seems if I apply the rules as stated Bamboo should be leveled in the SSR.
3.1 Whenever PTO Terrain (
G.1) is in effect, all brush becomes bamboo.
Bamboo is treated as dense jungle except as stated otherwise.
2.1 Whenever PTO Terrain (
G.1) is in effect, all woods become jungle. If not defined as Light, the jungle is considered Dense (
2.2). The term "jungle" by itself refers collectively to both types.
Jungle is treated as woods except as stated otherwise.
Bamboo should be leveled to 1/2 level light jungle per SSR.
And it does seem really weird that all that hill would be leveled but somehow the few hexes of bamboo was left standing.
