From what I can remember, the problem seemed to start happening after I downloaded and started using the pcc oxp, but I can't remember for sure. Is it possible that that oxp doesn't work with another one, like dragons or supercobras? Or am I just imagining things and every ship market goes through "dry" spells like this one?
Edit1: I just noticed that the pcc oxp isn't listed among the ship oxps. As such, I'm going to do a little test and see if that's what is causing the problem.
Edit2: I've done about 5 runs so far since removing the pcc oxp and nothing has changed yet...perhaps a little more testing?

Edit3: And on my last test ensorius finally had the regular ships back again. It does appear that the pcc oxp may have a bug in it. There's a link to it within the supercobra oxp on the wiki page, but not on the ships oxp list, which may have been telling huh? lol.
