That is a point that reguarly comes up around here, and I don't know why. TSL is a complete and finished product, it is simply a buggy product. The things that were removed (such as M4-78) were originally going to be added in patches like was originally going to be done for some of the places in Kotor. This unfortunately never came to pass, and because there are places where these things COULD happen, and the scattered remainants are there, people consider TSL to be unfinished.
It is not.
