MR problem
 

The first time i rendered an outdoor scene using MR for Global Ilumination, de render came out very good, so i saved the file for posterior shots! When i reopened the same file, everithing was fine until i rendered other scenes and the spot light, that i was using for faking the sun light, it changed location to the origin - DURING THE RENDER PROCESS!!! Can this happen!?:banghead:
