Lockscreen wallpaper issue on g930v with recent PI3 update

[AC Question]

G930v (verizon veriant) received G930VVRU4API3 update few days ago. My lockscreen wallpaper is set to multiple photos therefore it randomly rotates every time phone is unlocked. I do not use 3rd party apps for it. After the update I noticed that after few hours or so the wallpaper keeps changing to the default one (cloudy blue/pink/purple). I am not 100 percent sure this is because of the recent update but I can't think of anything else. I was wondering if anyone else is having the same issue.
