Heya,
I will add dead trees, never heard anyone chopping those lol
Added them in V3.07, will be live in a few hours
For rest of the post:
- Chop and drop works fine on the rest of the trees, probably issue with your setup
=> Make sure you loaded you current position and selected a range to chop in. Yo can see the range to chop in in game
- Axe upgrading, yes includes all until crystal axe, I don't see wy you ever wanna use any felling axe except for a dragon one though xD
