Steps I used to make points stick. Move fresh xbox profile to usb. Delete all Deadpool saves and cache off of xbox hard drive. Disconnect xbox from internet. Mod profile with new R&R'd GPD. Put profile back on usb and played game offline with profile still on the usb, and choose save device for game as the usb also. Points are there. Play game until you see a autosave notice on screen (Checkpoints did not work, need an autosave). Once you see autosave, you can connect back to xbox live. Played game online and the max DP points were there. Moved everything back to hard drive. Points are there. Good luck.
Yeah when I connect back to xbox live, it reverts me back to main menu saying" last played on another console" and when I continue into the game, the points are gone. Plus, when I was offline, I could not go into the Sai's weapon menu. It was glitched. Edit. Plus, I have the previous stuff I unlocked with the points, but they still need to be purchased. EDIT 2: I found Ccaveman hexedit tutorial and got the dp to 100mil.
