When making major changes to libraries (as you are), I usually do it a little at a time. This seems to avoid the corruption problem (which we’ve never been able to duplicate when looking for it). What do I mean by “a little at a time”?
1) Open the Library Manager
2) Add all (or some) of the emitters you want. You can create new folders too if needed.
3) Save the library, or even close the Library Manager.
4) Load another library.
5) Load the first library again. This is to detect corruption at the earliest point.
6) Repeat steps 2-5 until you have all of the emitters in the library you want.
7) If emitters need to be put into different places in the same library, drag them around now.
8) Do steps 4 and 5
Etc.
The point is to save the library often, and load a different library, then reload the library you are working on.
If you get a corruption, you can use the latest backup in the “library backups” folder — just copy it out of that folder and remove the “.bak” extension.
