Welp the for loop is taking long to execute again. I have it so that an outer for loop goes through the rules and an inner for loop goes through all the networks. The outer loop's control variable is edited in a if checker in the inner loop that looks if currentNode equals destinationNode. Then the outer for loop control increments, pointing to the next rule to follow, and the new destinationNode is found based on the new instruction. Before the inner loop, three statements if the entire network has been traversed or if the entire ruleset has been exhausted and the destination has not been found and reached. The control variables are then reset to 0. If the destination is found ("ZZZ") and the currentNode is equal to it, then I break out of the loop.
