I assume you mean "settable" by "can be set at the particular moment", and I suppose you have checked it by actually clicking "set route".56independent_actual wrote: ↑Mon Jun 28, 2021 19:39I often find this when routes are perfectly settable, but they don't get set. This error is far too general for me to file a bug report with any success of solving it. I think it has something to do about server restarts, but I do not have enough information to come to this conclusion.
I forgot that you might need to check the signal influence point, but if the routes sometimes get set then it should not be a problem.
Otherwise you should just file a bug report (do not think what might be happening, explain what is happening), or you might need to explain further. You might want to provide some details about your setup to make the problem more precise. I don't remember encountering such as issue despite running advtrains in singleplayer worlds multiple times, so this appears to be weird to me as well.
