I've started to run into an odd crash related to the BARb AI, playing 2 human players versus 3 barbarian AI players, two of which being set to aggressive. I'm not sure there was any update from this error, however, the other human player is not running into these same crashes, and is seeing odd messages related to SkirmishAI IDs when I try to rejoin.

Game will crash extremely reliably on the same second when catching up on rejoin, which tells me at least that there's something the AI is doing or responding to not being handled properly on my client, although there's very few changes between this game, and the many previous games I've played in the past month (at least 30 2v3, barbarian ai, two set to aggressive, one to hard). We had ended one lobby, started another with the same map, same settings, same AI, and had crashed in the same way, with the same error out related to SkirmishAI. As far as I can tell, the log does not seem to make any indication of what might be leading up to these crashes.

Additionally, we also play with scav set to neutral (with no AI set in lobby) which could add to the odd behaivour, but I'm not sure. Additionally, I should add (with the recent AMD GPU drivers being all over), I am on 25.3.1, though I have been for months without any real issues, and I doubt that's related but I'll add it just in case

#

I'm not sure if these are relevant, the AICOMMAND errors/warnings appear in the catch up when rejoining on the other player's UI, but we've not seen these before when rejoining prior to these particular crashes.

It doesn't seem tied to the map selection, more entirely tied to some sort of AI related issue. I've also reinstalled BAR to make sure it couldn't have been some install issue, and it will still crash the same way, without any apparent warning (in game) https://log.beyondallreason.dev/logs-20250406T0547-cT0EI_Et.zip

#

Upon looking at the player's replay, we noticed that once my client crashes, all AI players also basically cease to be as well, which I think might explain the invalid SkirmishAI ID warnings

After swapping hosting between me and the other player, it is pretty clear that coming across a Legion Fortifier, specifically a neutral scavenger one, **consistently **crashes the host. I think it may be due to AI related issues with the Fortifier when spawned as ruins?

Spring Crash: Access Violation related to AI/Fortifier

I was really curious as to what is causing this crash and may have found a way to replicate it. Begin a skirmish with hard AI on a larger map, with ruins (dense will make it more likely to happen, as a Fortifier is more likely to spawn). If the AI encounters a Fortifier spawned as ruins, they will attack it, and if there is a wreckage left to rez, they will rez it and that seems to be when the host of the game crashes, along with all AI players.

Confirmed. Ruins are ruining games

Fix applied, worth testing

This bug keeps interrupting my game over and over for some reason. I was playing the scenario 5 against AI. Can you fix this issue for me, I don't have any clue on why this bug is crashing my game.

Is it about Fortifier or Advanced Fortifier?

I have no idea
