I got a weird problem, I recently switched our hub bot over to 1.6.12.
What happened was that all channel specific records got lost ("well, not entirely, got them backed up"), but the bots stoped sharing channel specific records. Global records still works and all.
Now, the channel is set to +shared on bot the hub and the leaf.
The leaf has the hub as .botattr +ghp and .chattr |+s #channel
The hub has the leaf as .boattr +gs and .charrt |+s #channel
