Vector <t> too long - Error

Same here, act 3. I defeated the act boss and went back to town.
Now it is not possible to use waypoints anymore, "Vector <T> too long".

It is only broken with my Betrayal char. The standard league ones seem to do fine.
Would love to get some feedback.

I get the same error when zoning into Vaal Ruins 1, tried waiting for reset and restarting, but still happens, cant progress any further on Betrayal.

Edit: works now, unequipped MTX o_O

Received Vector <T> Too Long crash upon entering the Dread Thicket. Windows 10 64 bit, GTX 1080. Did a pack check and it said everything was synced. Looked for crashreport but didn't see it in the directory so I assume it was removed at some point. When I logged back in it showed Dread Thicket as having been explored now so the server recognized me entering it but the game client crashed during that load. I was able to re-enter the dread thicket before the session expired fine after though. I'll also note this is the only crash I've ever experienced with POE and been playing off and on since launch of the game.

Im also having the same issues I was going through the vaal ruins and clicked on the portal and was booted out with the error vector T too long I tried a few times and kept getting the same message went to sleep for about 4 hours came back and got the same message.

I can't progress through Act 2 as this error crashes my client every single time I try to enter the Riverways. So I guess Betrayal League is 1 1/2 acts this season? Quite frustrating.

I've just tried getting into a zone with my mtx on and I got the error. I took it off and tried again and it worked. For now it seems as if the mtx is causing this error.

I am not wearing any mtx at all and i have this issue right now. Super wierd.

same problem in act 3(when entering locations). unplayable:(
update: problem is solved for a while. What helped? I just stayed in the town act 3 for a while(a minute or so) before teleporting anywhere. Probably error occurs because textures or something like this don't load on time.
It doesn't solve the problem completely, but easen it much. Also it seems like this problem happens on low and mediocre performance PCs.

Have same issue everytime I try to enter "The Chamber of Sins Level 1".
Steam local files integrity check found nothing wrong.

So it looks like I am unable to continue playing PoE until fix :/

Received it again today. Exception: vector<T> too long. Got it when going through town portal back into Kaom's Stronghold. Back into because I was just in town to sell stuff and had already cleared half of the instance so it can happen when you've already been fine in the zone up to this point. Re-logged in but portal was gone. Edit: went back to zone through the waypoint in town and my cleared area was still clear. Again, never had ANY crashes before in my years of playing this game before these started after 3.5.
