How to diagnose game CTD'ing?

[Elenear]

Hi all. I have a heavily modded Fallout 4 via Mod Organizer 2.

 

I have well over a 100 hours in this playthrough. It has never crashed before (well, it has but extremely rarely). I've had a longer break from the game and now after loading up ANY save the game CTD after a few minutes.

 

I am an experienced modder, I have made some custom patches for the mods conflicting in my modbuild. All of the mods are up to date, including F4SE and Unofficial Patch.

 

I run the game, I play for a few minutes and then it just crashes, no messages displayed. I tried loading up a few different saves from the earlier time of the playthrough, but it crashes on every single one of them after just a couple of minutes of palying.

 

Resetting cells didn't help (I slept for over 80 days, which I believe is the full reset on Survival mode.)

 

As I said, it has never really happened before, I was able to play over a 100 hours with this modbuild without any issues, apart from a VERY occassional crash. Now it is pretty much guratanteed :sad:

 

There is nothing in MO2 logs folder.

 

Are there any tools that can help me diagnose the CTD's?

The three I use are:

• Buffout4 (47359) which if properly setup gives a crash log of your final moments. The big setback is unless you have a degree in programming it is almost impossible to read and you have to rely on others to maybe answer your question. But it may give an idea where to look. currently i have been having a hell of a time with xaudio2_7.dll, but at least Buffout4 is letting me know to look there.
• Resaver (Fallrim Tools) - http://www.nexusmods.com/skyrim/mods/76776/? or https://www.nexusmods.com/fallout4/mods/22633 is a great tool to examine your saves. It can look for issues such as unattached scripts or possible issues with script elements such as suspended stacks. Kinggath speaks about it on his SimSettlement web site
• finally and i expect you have both is LOOT and fo4edit. I just use LOOT to ensure I haven't done something totally stupid, but not in organizing my mod order and fo4edit to see if my order is causing serious conflicts that needs reorganizing or a patch file

Good luck

Thanks a lot! I'll have a look at Buffout4 definitely! I work in 3rd line support/devops type of role, so hopefully will be able to interpret the logs :)

 

Resaver looks useful too, especially for looking for detached scripts. I use both Loot and FO4EDIT too to create my own patches and I couldn't see anything wrong using those 2 tools... I will try the other two, thanks again!
