I don't know offhand if we track it anywhere yet or why it would be randomly refreshed after logging in, but here is a note which I think is from Derision back from RoF1 (which I just copied to RoF2):
https://github.com/EQEmu/Server/blob...rof2.cpp#L2344
If we start passing a timestamp there, we can probably prevent the random refresh timers client-side for Mend. Since it currently sends 0, I am not sure why it is randomly working. Unless, maybe that is incorrectly identified in the PP and it is actually picking up a value from a mis-identified field somewhere.
