Hi, we have the same problem.
We want to find wich object has the negative surrogate to modify it, but we cannot find it.
We export our model in XML, but it's difficult to find what we want. We also used the function "Output File for Implementation Names". I see 9 negatives surrogates, but there are SYSTEM objects and I think that it's normal. But I tought that I could find another object...
Does someone know how to find wich object is the negative surrogate ?
It is important to take the time to fix it ?
Can we simply change our Plex.ini as it wrote in the George's document and we will never have this warning?
Thanks
Eric
