Am I Mettaya?
I actually recall something about distinguishing between an attempt to blow, versus a legitimate Present Time Problem that is interfering with the PC being in session. You're supposed to HANDLE the PTP, and then continue the session.
Well yeah, that's basic TR-4, but i seem to vaguely recall this LRH tape which seemed to assert that in objectives, things are different.
It seems i would have been crammed big-time otherwise, and if i had been crammed over that, i would have remembered.
But WTF, this was mid '80s and i don't have perfect recall like them Clears.
