Not sure what happened here. Yesterday it was fine. This morning it crashed on load. Tonight it continues to crash.

I pushed out a minor release yesterday, and that loads just fine, so it's not the end of the world but I'd like to know how to diagnose this. I have a suspicion about a bit of frankenstein nif editing I did, but without being able to load the mod...

Any suggestions?

Load it up in TES5Edit and see what's going on?

I've never heard of bad nifs crashing the CK until one actually tries to open the record for it. Usually it'll just show the no mesh exclamation point.

TES5Edit shows no errors, no conflicts...

I've not had a chance to look at it since I posted. Maybe I'll copy over the loading esp and work from there. If it doesn't load then that too will tell me something.

[edit]

Yesterday's release loads just fine. Copy that esp into my dev folder and it crashes. rename my hacked nifs for .nifx and it loads again. It's the nifs all right.

I wonder what I got wrong.
