I guess that is a result of lack of work getting done on it because of only Rampage working on it and also real life getting in the way. 
Well one of the issues right now is the modpack. Sid told me this would happen, but I was adamant towards designing missions up until the problem actually hit. And now it has. Many of the ships, especially the ones encountered later, need updating. This also includes weapons. So as you can imagine, this will involve not only lots of tedious table editing.
After I finalize the first 10 missions, they will be made available to the rest of the INF staff for testing. From then on, I plan to strip down the INF SCP modpack and rework all the ships and weapons. As you all know, Woo is working as hard as possible to bring you guys INFA. But I will do my best to coordinate with him in this effort.
