The problem was that, the game unpacks only attributes for boss game, and overwrite my converted attributes, and after boss game it restores the attributes from another packed file, now those 2 packed attributes are converted also.
I found another bug in the saved game ( i created a save game state from memory from you snapshot
) boss game do not update saved game in memory, i had 2 choices:
1 do not modify on saved game setup, and copy the content to save game memory
2 modify content, and save save game memory also
I chose the 1st solution, it can cause some positioning issue after die if new checkpoint is not reached, but i did not meet serious positioning issue.
