Linetypes won't save

[apost201]

I created 3 layer states, continuous, hidden, and dotted, for those respective linetypes. I created a drawing using each layer when appropriate. I saved, closed, and opened the file back up and the linetypes were all replaced with continuous (or hidden, etc. it just depended on which layer it opened on). Why is this? I've had this problem before but never figured it out. Why won't AutoCAD save my linetypes?

I've never had that problem before. At a guess I'd say you are either not setting the layers correctly or the file is not saving correctly.
