Hey Cleaburn - how's it goin' old pal?
I get those symptoms mostly when I point and click movement orders to an individual regiment, even with its' brigade commander TC'd. Most amusing is when a regiment does the twirling Dirvish Dance. :silly:
Most frustrating is when I want a regiment to advance a few yards (5 to 10) to just cross the 160 yard threshold, I often have to click way out front in order to force my cursor to click a spot dead ahead - damn cursor wants to click to one side. When the regiment gets 5 to 10 yards forward and I click halt; then it marches back to its starting position.

I chalk these weird movements up to friendly regiments being too close.
