New UnstableCO Client added to download links.
I didn't have a 5065 patch client handy and used a 5069 client originally. Turns out CO changed the + item composing interface in 5066 so the 5069 client was making it seem as if there were bugs/glitches in the composing system (that would let you keep your + items after using them, but also not save your composed item to the databse when you logged out).
However, there is no bug/glitch, it was just the wrong client sending wrong packets! Woops... sorry. Go download the new and correct client from the About page and all should be well!
Sorry NotCpHunter! :P
