Trouble! I downloaded the latest version from bitbucket, and now the HX parts show nowhere! I extracted the mod to root folder of KSP just like what I did to the previous version (which worked fine). Also, I noticed that models of HX parts are directed to B9_Aerospace folder instead of B9_Aerospace_HX(!), so I moved "Parts" to the former one once and it didn't work. Besides, I changed .cfg model directory of several HX parts to B9_Aerospace_HX and still nothing happened. P.S., I deleted all cache files before everytime I tried.
