Comingling personal funds and business funds is pretty common with scenarios like this. That, and having good cash flow to make the financial errors easy to overlook until the "house of cards falls/fails".
With his "Glass Mansion on the Lake", he pulled welders to work on it when they had existing work orders with cut materials that went unworked.
Add to that, moving assets around to different people and family members to protect it from a bankruptcy filing.
In the end, the billables from vendors and cash flow went "upside down" and it was over.
At this point, I'm guessing some financial savior came into the picture to fund a restart. Whether their bad reputation will be remembered and can be overcome remains to be seen. If they have a successful restart, I would not be surprised to see a bigger company come in and "buy the assets" in a takeover similar to Kubota and Land Pride.
