Why the reinforcements never showed up?

[Shinobi]

I played STW warlord edition several times. But I still do not understand why the reinforcement never showed up? I attack a province with more than 16 units. 15 unit were routed and One general unit left. The reinforcement never showed up ? What's wrong?

After that happened, I decided to automatic calculate the battle if I attacked with more than 16 units.

Krast has never had that problem.

Always got the extra guys as reinforcements.

But, they only come on when the last of your guys is off the map, unit by unit.

Sometimes guys get trapped in trees, etc and can't get off map.

I too think that there is something odd with respect to friendly reinforcements and have a couple of posts on that subject. I have waited in vain for my reinforcements several times. However, today I had a number of large battles and my reinforcements did seem to show up somewhere close to the expected times.

I have a hunch that in the orignial STW they just showed up like clockwork while now in WE there may be some probabilty thing going on. Does anyone else see it this way or have inforamtion on the inner workings?
