Works well enough, couple things I noticed is that when the brazier goes out and it's chopping roots, it tries to run to light the brazier, but stops like 1 square away without actually lighting the brazier, only to return to chopping roots. Doesn't have this problem when it's already at the brazier depositing kindlings/roots.
The other thing is that often when it's depositing kindlings/roots it keeps clicking on the brazier, constantly resetting the timer for depositing despite not getting hit by wintertodt.
