Any one know how to trace what happened when you start getting these

It has something to do with some kind of acad bug when working with xrefs
but the cryptic nature is annoying...
I'm pretty sure those arent' handles or object ids....but what are they and
how to find out what went missing???

Thanks

nope,
this occurs in dwgs which have been worked on with no problem for months
when using multiple xrefs and making various changes in xrefs, this occurs
maybe if i did a purge on an xref, and that purge deleted a block def, then
in the parent dwg, maybe the xref|blockdef became undefined?
Though it doesn't seem to be related...
In other words, maybe I just changed some lines in an xref, then later in
the parent dwgs I get this msg.

I also get a lot of Error on save recommend recover this dwg after doing
anything with an xref...
This isn't every time of course, very intermittent, but it definitely is a
bug in acad 2008 when dealing with xrefs
for example ever since 2007 you occasionally end up with duplicate layer
names in dwgs that use xrefs
of course that's *impossible* right??? but in fact it does happen with some
frequency
So I do claim it's a bug. I wrote a vba just to detect duplcate layer names
and delete the dups because eventually they would end up corrupting the dwgs
to some extent...

2008 appears to be more sensitive to the crap that acad bugs leave in the
dwgs with xrefs and so I get a lot more of those Error on save Recommend
recover dialogs in 08 than I do in 07

I get these every now and then as well.
The duplicate layer problem seems to happen when you refedit in place an xref and add objects from the current drawing, whereas I don't think it happens when you use xopen and paste the same objects in. Of course it happens so rarely that you can never actually track it down.

Right, I had forgotten that part...about refedit...that definitely seems to
be a less than perfect implementation...

just refedit an xref and a bunch of $0$ layers are brought into the current
dwg for absolutely no good reason at all 🙂

purgeall has become my secondmost used command...after save of course

Do you have "Create unique layer" checked in your refedit settings. (I never check that as you do get $0$)
