How to Repair a Broken Project? - Fatal Error related to Animation State Machine

[Vaei]

Using UE4.6.

I was working on my animinstance and setting up the state machine. I was doing a repetitive task that has been done before, nothing out of the ordinary. Then it froze and crashed. Now I can open the project but if I attempt to open any blueprint the engine crashes again.

The error output claims there was a fatal error when casting ‘AnimStateConduitNode’.

How do I fix this? I don’t think there is a forum for this so I posted it here… I did way too much work and fixed way too many things to lose it, it’s bad enough I lose the hours/days until someone knows how to fix it

This is the error output:

Unknown exception - code 00000001 (first/second chance not available)

Hello,
you’ll have better chance to be helped by posting on answerhub (link is on top of the page) but as we are saturday… Try to check your autosaves and (with saving actual file) check if your last autosave is not too much far from where you are with the usual one to be not to bad to use.

Hello,
you’ll have better chance to be helped by posting on answerhub (link is on top of the page) but as we are saturday… Try to check your autosaves and (with saving actual file) check if your last autosave is not too much far from where you are with the usual one to be not to bad to use.

Thanks for the response. Answerhub is much much slower and rarer to get an answer so I usually just post here.

The autosave loses a bit of work but it is usable. Thank you for pointing that out. If it happens again I will try to remember what I was doing when it occurred so I can make a bug report.
