Anybody else make silly mistakes

I forgot to place units a few times (years ago) didn't notice till the games got going.
Only thing they might have been good for is defending an airborne drop.
For me this can only happen on a very large map with way to many troops, so my misplaced units didn't actually effect the game much.
Chances of it happening in the present close to nill.

Now you have said that remember a terrible phase I had of deploying & going wheres my AA, forgot to buy any again.
