At 2:35am this morning I noticed that the Murakami Steamworks line of popular ironclads (such as the CSS and USS historical models, as well as the David) seems to have been withdrawn from the market.
I am not sure if this is because of scripting updates or anything, but a quick visit to the company's HQ in Erlberg only showed up an empty region for sale.
I have contacted both Mr. Murakami and his colleague to see if I can get some more information. If so, I will post it here soforth.
Update: I got a reply from Mr. Murakami and the company is in the process of moving to Caledon. Meanwhile they had to take down the server. It might be down a month or two, unless they find anyone willing to lend some land for it until they are re-established.
