Perhaps the live game produced a different error. Keep an eye on it

About the Llama error: Do you have a tuning mod or a retuner alteration of the SimRoutingComponent.kDistanceMustSaveInOrderToUseSubway value?

Yeah, I think, I have done it in Retuner so Sims can ignore the subway moreso when the distance is not that far and my Simmies could just walk to it destination. I've took the values from somewhere over here, I think, discussion between you and Sarah_Sims.

Or were the value mentioned in somesort of Tuning mod I found, which I then added through retuner.

Found it: Retuner Member Created Tuning Files

Do you have it set to 15? I think having it set higher than default is likely causing the llama's to break. It's not really your problem, more of a FYI or observation I found while pondering the error, I believe you don't even use them? It looks like the problem begins when twallan does hacky things and replans the route when it can't use them because of that value. Just not sure if it's fixable atm.

I am not so sure if its exactly 15, not in game at the moment, it could be higher then that. I'll check it once I have the chance and soon will, I'll look if 15 is doable and an even higher amount, till Gohere spits out that error on Traveling, so we can determine the max value of that tuning where its safe to use without Gohere hicking up

Guess what .......(drums, drums, drums)

It is set on -1,000. I think I gotten it from a Discussion or Tuning File somewhere, cause I was so annoyed of Sims routing to the nearest Subway Station to route to another Subway station near my intended destination, even if it took it much longer to do it that way, while they could just walk to there.

I'll see if a positive value can revert the ill effect what I gotten so far, from 15 to a higher value and see where Gohere breaks /or/ stumble over it

With the latest test version traveling to the future through the Time Portal just seems to fail outright, no matter whether I take one or two sims. The game stops loading relatively quickly and returns to live mode.
I tested this with one and two sims, using only Error Trap, Overwatch and Traveler under their standard settings. I can also confirm that traveling to Chang Simla through the computer Travel menu with two sims works without problems.

@PentaP - Hi there. This particular thread was actually concerning different issues with a much earlier beta release version of Traveler v87. Although it might not have seemed like the obvious thing to do this time, it would have been better to start a new thread about this ITF issue with the newer v87c.

Anyway, I'm not seeing this issue. If you're getting it when attempting to use the Time Portal directly, have you tried using a sim's phone to travel to OL when in the presence of an activated time portal to see if you get different results? Or, if you had already been doing it that way, have you tried using the portal directly?
