Seeking Pathing help

I'm sure someone has figured this out. Its driving me nuts

So I'm attacking a village, bombers just went in and blasted a hole. Giants marching in with wizards and witches in tow. A straight path to the town hall. Then.. I drop a pekka and instead of following the others, he goes around the perimeter. There have even been times in which I dropped two, at two different spots thinking its a drop location factor but I get the same result.

So is there a trick to this or some sort of formula I should follow to get certain units to commit to going right into villages when the walls are down?

Clear the whole side of external items/collectors before dropping golem.

The exterior structures will forever distract your pekkas and those that don't target specific buildings. If you watch Clash with Cam you would see his base have a golem trap where Tessa's pop up from the side so the golems won't go to the centre, here's a tip- Clear exterior structures, check for bombs and ensure you really have a path.
