Issue
Thuamcraft Golems don't drop logs when breaking Greatwood (from Thaumcraft as well)

Do other logs drop when they break them? Is the area claimed?

we aren't using chunk claiming and yes the same spot I tested oak, it worked fine, Greatwood has Iron tier harvest requirement would that cause the issue?

Yes, that would indeed cause the issue :/

Can you upgrade the Golem's mining level?

I'm afraid not. I'm kinda torn between reducing the harvest level required, or letting the issue be.

Not that I can tell, it's already got the block breaker upgrade (it uses diamonds in it's recipe so I'd imagine it's probably intended to able to break things at diamond level) but it doesn't have a mining level I don't think.

unless there's some way to change that in the config or something.

well I don't know if there's another way to automate thaumcraft's trees... since they don't usually play nicely with other mods...

There are many :) Cyclic's Forester for example
