Not really a bug.. but it is bugging nonetheless
When you first talk to your ox, the options are as follow (from memory, only the first two really matters here):
1) Unload Pack
2) Rename Ox
3) Lead Ox
4) Tie Ox down
5) Nothing
But once you unload the pack... and wants to put it back on, the option are "reversed":
1) Rename Ox
2) Load pack
3) ...
Could it be made so that the renaming option stick to the second place.. or even better be put at the end of the talk option, as it is not something one will do very often.
