Something weird has happened to the 2.5m RCS fuel tank (the FL-R1). In my install, it looks like this, and it's been this way since 1.4.
As far as I can see, it's using the new texture on the old model. I'm not sure how to fix this -- I've even had a look in the config file for this part, but I'm not sure what to change in there to fix it. I'm using Firespitter Core as a dependency for another mod and that's the only mod I have that could be causing this. (I can give you my full modlist if you want though).
Any ideas??
