AS2012 will not keep user data input

I enjoy tweaking my destination weather to make it hardcore IFR. This includes low overcast scenerios or heavy thunderstorm activity complete with windshear and severe icing and turbulence. I mistakenly purchased ASE and then upgraded to AS2012 in search of that ability. After discussions on this forum as well as unanswered trouble tickets I am convinced that HiFi not only has no solution but will not even address the issue in dialogue.

Here is the problem:

Inputting CB layer with severe turbulence and instantaneous windshear (very common RW scenario) will initially adjust the metar and GUI to reflect the changes but within minutes (sometimes seconds) of returning to FSX, it alters the metar to scattered Cu with occasional turbulence. The only parts of metar not changed: visibility, precipitaion, temp, and wind. The same thing occurs when inputting solid overcast. FSX displays scattered clouds!

From what I have gleaned from trial and error, ASE/AS2012 does not store cloud data but instead randomly creates it when it displays the station weather. Since the metar information it uses does not indicate cloud type, HiFI simply uses a random guess and it can often be quite different than actual weather. And it only uses stratus, cumulus, and cirrus and NEVER Cumulonimbus.

The exception is that occasionally (very occasionally) it will display whisps of CB enroute or if the original (unaltered) metar specifies CB then it may (again very occasionally) actually display them but without windshear or severe icing/turbulence which are the attributes that make their presence dangerous and challenging.

The whole AS2012 update apparently was only to target the REX crowd and was concerned with eye-candy rather than improving the realism of the weather engine.

Now that HiFi no longer monitors this forum any short-commings with AS2012 apparently will continue to go unresolved! I wish there were other creditable weather engines available on the market. To me, if you won't even depict thunderstorms or solid overcast weather, what is the purpose? FSX displays fair weather skies without need for any add-ons.

And that is my rant!
