Can you give more info? Are you use an outfit that autoloads? Does the outfit have a size or model modifier?

[ghost]

@thegrb93 As for the outfit - yes, put it in autoload, only changed the size of the hull horizontally and vertically.

@wrefgtzweve I'm using the "develop" branch of the latest version.
