i can't attach image so i just copy it here.
StateMachine.cpp:159:void_cdecl
gladius::scene::unit::state::StateMachine::animateAction(constclass gladius::world::action::Attack &):Assertion"worldUnit.getOpponentTile()" failed: No opponent tile.

It seem it happen randomly, i load 3 last turn save, it can happen at any future turn, sometime i go over the bug, next time i crash... and it happen in AI turn, seem AI do something with each other and cause bug

Same here, started an ork game right before the patch hit, getting the same error message.

f@ck, they screw my save game, i am enjoying it , turn 114 already

I noticed, that it happens to me when tyranid hive crone kills something like umbra. Donno how to fix that thou

Same error. Worked fine before the update, but now previous same games are crashing with this error. Has anyone tested if it still occurs with a new game (100-200 turns in)?

I also got the error for the first time now during a multiplayer game. (we started that game on December 1st, before the Ultima Founding update)
It first crashed during the AI phase in turn 97. After reloading we were able to get to the next turn but got stuck in turn 98 where it crashes every time.

(I play with 2 mods. "FACTION: Farsight Enclaves" by dexgattaca and "More Map Sizes, Options, & Difficulties" by Skirata)

We have the same Problem -.-

I just got this crash.

Yep, going to start a new game and see if this is only applying to pre update saves

It's not. Mine was a fresh game, post update.

My game started crashing with the above error about every 2-3 turns since the update, now I'm at a turn where it crashes every single time I end it.

Crashing on End Turn -- but this was a new Primaris game.

Ultima Crashing Bug

I am having the same Umbra problem and crashing after I roll my turn. I have had to restart over a dozen times in less then 80 turns. WTF! The crashing seems to be getting worse with every update.

Yea I have the same error. Trying to complete vs 2 Chaos with Eldar and keeps crashing. I thought it was because of the mad spawning they've been doing but seems to be a common thing (thankfully). Hope it fixes soon

so this sounds like they dont got there ♥♥♥♥ togther and 3 patches in a row that already shoud fix that problem only shift it to another error message every incarnation?
