Mission Editor HotFix ME1.4.8
Althought not critical, version 1.4.8 fixes the issue when one of BuckeyeBob's cloud file ("OFF_BB Overcast with Light Saturated Clouds.xml") has not been recognized by Mission Editor and kept unmodified. Thx BuckeyeBob for pointing it to me.
My apologies for this inconvenience.
Installation Instructions: Copy, pls, above executable file to your Mission Editor folder overwriting the old executable.
