How do I check which mod may be causing constant crash to desktop when entering the wasteland worldspace near Novac?

[NukaCooler]

I've been playing a fairly heavily modded game, but haven't had any problems at all until I got to Novac. I crashed twice on the loading screen after exiting my hotel room, after which I `coc novac` and everything was good for a while. I completed Milo the ranger's quest, and after coming back to Novac I crashed again twice after exiting Cliff's bungalow, a `coc novac` fixed that as well, but then I crashed walking up to Ranger andy's bungalow (without having pressed E to enter it yet).

I haven't changed any mods or load order since then, and neither FNVedit nor Wrye Bash throw up any flags.

Using Mod Organiser, launching through the 4GB launcher NVSE with Lutana, NVAC, NVSR, and many regular mods.
