Reiche and Ford legally had to be contacted and they declined to bid and they didn't challenge Atari's right to sell.
Where was that? I did not see any documentation showing
direct notification, refusal or any contact whatsoever between counsel for Atari and/or that of the court and Reiche/Ford.
That would be a violation of the 5th amendment.
Your understanding of the 5th Amendment seems to be flawed. Read;

You seem to imply that proper due process took place, but there's no evidence of that. Reiche and Ford seemingly did not receive proper due process either due to a procedural mistake or misunderstanding on Atari's part as to the fact they needed to contact Reiche and Ford.
The court operates on the information has available to it.
Correct. That does not mean that upon a discovery of a mistake that said courts judgment can not be over-ruled.
It was Reiche and Ford's responsibility to present their contract declaring that they have first right to purchase the trademark.
So long as they were properly informed, yes. Doesn't seem like they were though as there is no documentation, or mention of documentation, indicating the effort of proper contact or any following correspondence.
They did not, ergo, the bankruptcy terms apply: Reiche and Ford forfeit all claims to it.
The evidence(lack thereof) does not support that statement.
Reiche and Ford would likely have to sue Atari
Except that Atari is not the responsible party to Reiche/Ford. As direct result of the sale, Stardock accepted and assumed all rights and responsibilities for the assets in question, including litigation that may stem concerning it. Reiche/Ford are pursuing the correct party. If Stardock loses, then they can go after Atari for improperly representing the properties being sold through the bankruptcy. That is the proper procedure.
Statues of limitation are not as concrete as that. If a mistake was made in procedures and the rights of Reiche/Ford were violated in the process, any statues of limitations can easy be, and often are, set aside.
but they still do have potential copyright claims they can make against Star Control: Origins.
Correct.
The burden is on Reiche and Ford to make their case that Star Control: Origins violates their copyrights.
Given Wardell's public statements and the release of the game which seems to contain elements of IP owned by Reiche/Ford, Stardock is in hot water. The fact that a court order has already admonished Stardock of improper behavior, it seems entirely likely that this case is not going to go in their favor.
