>>Have heard over the years about the flaws in UWP generation in some
of the older versions of Traveller something about habitable planets
around sun that couldn't support them, this is briefly mentioned on one
of the 1248 books, just before they give alternative data, though they
don't mention how they came by the data.
Does anyone have a recommendation for the best set of generation rules
or a set of house rules that fixes this?

Well, 1248 had the help of an astrophysicist, but even before then it
was pretty obvious that an M8 V wasn't going to put out enough heat to
keep an agricultural world from being an icebox.
There are several sets of gen rules out there. It all depends on what
degree of realism you want to apply to YTU. If you want as realistic as
possible, check out EDG's system:

There are some rules at the end of Mongoose's "Traveller SRD" file that
explain what you can do to fix existing UWP's.
You can:
Bump up planet sizes to retain atmospheres.
Change stars so that they provide the right amount of heat for your worlds.
Eliminate "D" stars (white dwarves) from all systems that still have
terrestrial planets with atmospheres.
Avoid putting habitable moons around gas giants--the radiation belts are
brutal.
It's late so my brain is shutting down for the night. I'm hoping someone
will type up the others that aren't springing to mind right now.
