I have tested the Rose Castle several times, and am no longer getting CTD's. I would like four or five people to volunteer to test out the ship in a single mission to try to confirm these results. I don't want to release a BETA to the general community, because some inexperienced moddrs will probably try to use her in a campaign and then complain if they get a CTD. So if anyone is interested, post here. I will upload the ship on rapidshare and send a link in a PM.
I may add a small crane to the bow of the hull .obj file later, and raise the forecastle. But that will come later.
