I’m not sure it’s alright if I keep bumping this thread. Please let me know if I’m annoying or disturbing.
I found something useful, something seemingly trivial yet successfully relieved the problem which has been troubling me.
I’ve been rotating the map again, again and again just to understand whether if a path is blocked in a forest. The trees can play tricks on your eyes. Especially when there a lot of trees, overlapping in your sight. IMO the following method is better than rotating map, of course it is even better to use both approach.
