Problem - With a simple and small max patch (57KB), I am trying to build it as a collective. I do all the normal stuff, go to File > Build As Collective, and in that window I include the 3 externals I'm using and the one abstraction. I hit build and sometimes max crashes, the other times it complets. But the mxf file is corrupted, it seems that it didn't include some of the basic max externals like message and ubutton.
I tried restarting max a few times, and even restarting my computer. I actually built this exact patch, with a view variations, a few weeks ago with no problem. The only difference is this was before the 6.0.7 release.
