If you use both of the above mods, you may come across Brita's UIMP45 weapon with the Cosplay's UMP45 character card icon.

To fix this, simply locate the UMP45 Texture in Cosplay mod directory, and rename it
Then go to the Character Card file in the Cosplay mod directory and rename it to what you named the texture file.

Putting this here to notify Cosplay's mod author and anyone who wants to make a quick fix and knows their way around editing files.
