So it is. Deleted.
Confirmed issue. There are no large oak trees generated in any forest biome on any of my maps.

Can't find any large oak trees in forest biomes on my side, can confirm this too.
this must be fixed!
It would be very sad if this was intentional. These trees give great variety to the forests and biomes need more variety, not less.
Confirmed.
yeah i know, but still i doubt it is a feature, jeb probably accidentally removed them whilst recoding the forests or something
oh, can't this be reopened in favour of a better description (because large oak trees still generate in Jungles and Extreme Hills, just not in forests)
please can this be reopened in favor of better description, this doesn't apply to Jungles and Extreme Hills
um... dude wrong bug report
