Manually finding *feasible* route through network

Hi. I have a model with a network, in which I need to manually find a route from one Network Node (source) to another one (destination). I managed to do this using the getnextnetnode and getnextnetnodeoutputport commands to progressively step to the next node in the optimal path. However, this seems to break when I use a 'Q'-connection to close the path in one direction. These commands will keep giving me the same edge, even though it cannot be passed in that direction and even when another path with all green arrows is available.

Now I found out that getedgedist returns -1 for such a closed edge, which allows me to find the problem, but I cannot solve it because I cannot ask getnextnetnode for an alternative.

Is what I want possible at all, without implementing the path finding algorithm manually? And is it correct behavior that getnextnetnode actually returns edges which are not passable in the given direction?

Thanks in advance!

Hmm, sorry, I tried to reproduce this in the latest FlexSim version and could not. However, it was broken in the version that the client is using (7.3.6) so I guess the answer is: please upgrade
