I got the idea for this guide after doing an experiment on whether img costs go up after removing items and replacing them. The img costs always stay the same and do not continue to go up after removing and replacing. (example: if you have 3 of same item, the cost will always be the same as placing the 3rd item). However if you wait until all 3 are depleted and remove them all then replace them all, you get the lower costs placing numbers 1, 2 etc.
I have determined that i will prefer to just remove and replace most of the items because the time it takes me to earn the img is shorter than the time to collect the materials and the time it takes for the tool units. You also get resources when you remove the item as opposed to spending time and resources to restore it.
BUT I MADE THIS GUIDE ANYWAY!
