I managed to edit and load in the bot based blueprint to use t2 miners, and was suprised that it was smart enough to place poles as needed, props! However it does not seem to place active provider chests as the blueprint has. The default for some reason has wooden chests at the back of the miners? Can you explain this or what I am missing? Thanks!

I suspect you've clicked on the Dummy entity button with an active provider chest, click on it with a wooden chest and it should all work again.

The dummy entity is never placed, it allows blueprints to spaced further apart than they would be otherwise, take a look at the Spread out example to see what I mean.

Edit: You'll also have to reload the blueprint after doing this.
