RTF is a global modification that replaces all towns in the game.

I don't understand, I didn't group anything into any groups... I just created a global and attached models to it as described in the tutorial.

There is no global; there is trygggggggggg:Global, which contains something, but it's definitely not models; the models are below.

Here's a screenshot of trygggggggggglatie - this is not a dress model; it's a group of models consisting of one model, tryggggggggggolySurfaceShape1.

The same applies to everything else.

... the forum keeps inserting smileys where they shouldn't be.
