Unity 5 18b worst than 17b :S

The “cloth” system continue exploding when build the game or when generate prefab and now the Editor no respond when stop the editor or when build finish:

Unity 5 - 18b Editor Crash.

Unity 5 18b - Cloth Explode

Sorry for my english.

Both videos are set to private.

Ups, sorry. Work now.

I found the problem with the editor. is a bake problem. Solucion: “Clear Baked Data” and bake again.

Any suggestions for the clothes?

Cloth got fudged in beta17 and is still broken in 18
