And that would gain what? Oh yes, confusion, because everything else in BM is turn-based.
Except Priest and Adventurer travel, which is either instant or on a countdown system.
Are priests and adventurers going to travel on a turn-based system? I imagine that the delay in priest/advy sea travel is probably due to this very problem. Just make all classes travel on an hourly system and it will be fairly simple, I think.
Load/unload could still take place on turn changes, because that's when the tide is changing (or whatever).
