Some commands just fail if you don't finish them in one uninterrupted
stretch (MOVE, RESEARCH, EXPLORE, USE, etc.) Others credit the noble
on a day-by-day basis (BUILD, STUDY, REPAIR, RAZE, RECRUIT, etc.) and
normally terminate when the task is done.
All but three of the latter group have an optional parameter to set
the maximum number of days to work at the task. Why are STUDY, BUILD
and RAZE different than the other commands? I agree that STUDY may
belong in the all-or-nothing group of commands but otherwise I'd
consider allowing the optional [days] parameter for all three.
I still can't see how this would allow abuse since we're already
being credited on a daily basis and the STOP and MOVE commands provide
artificial albeit restricted termination spots for these commands.
I promise I'll drop this crusade after this post gets shot down. ;>)
