Comment (by antoniou79):

 The error message comes from CLIP() calls. It means its parameter limits
 (amin and amax) are not ordered properly.

 However, the real issue here seems to be that a video loop is loaded(?)
 with 0 number of frames, which then, in conjunction to  certain parts of
 code assuming that num of frames are > 0, results to unforeseen "-1"
 values. eg. in Object_SetView() (engines\ags\engine\ac\object.cpp)
  (int)_G(views)[vidx].loops[loop].numFrames - 1
 evaluates to -1

 I don't know why the faulty loop has 0 number of frames though.
