issue with fnis creatures pack

[Begmysweet]

I use MO2

Issue is when I install fnis creature pack the FNIS behavior erases itself no matter what I do. Not sure if others had this problem but my FNIS behavior deletes itself from MO2 also. Now when I uninstall both and reinstall just the behavior it works fine. Just when I install the creature pack it does this. Really confusing as to what I'm doing wrong.

FNIS Behavior and FNIS Creature pack by default will be installed under the same name. When you attempt to install two or more mods with the same name MO2 will ask you what to do, you can:

• Merge: keep the old files (in your case the FNIS Behavior) and add new files on top (the Creature pack). <- this is likely what you want to do.
• Replace: old files are deleted, new files are installed (sounds like what is happening to you atm).
• Rename: the new files will be installed under a different name (the one you enter here) and the old files will be kept intact in its original location. <- you can also do this to keep FNIS Behavior and FNIS Creature pack as two separate folders/mods (listed in your left panel).
• Cancel: you exit the installation without making any changes to already installed files.

You must pick one. MO2 doesn't skip this question or chooses for you. So you're likely pressing Replace really quick without reading or your MO2 install has acquired consciousness and is planning to kill you.
