Off the grid lot challenge keeps lot from loading/ Error 109:f967dc7f

Since the last Update, I have the problem that my game gets always stuck at the loading screen to my sims hous. 

I have always played in houses on an 20x30 lot with a lot of details, but i wanted to try something new mad a new safe file and startet a little challange for my self. which was inspired by James Turner.  i startet with 0 simoleons al lot challanges available with one goal after the other. The safe it self is only a few days old. i used some cheats to help me when i was stuck, i only have 1/3 from my packs installt and also use some mods and CC.

Now my Sim has a child a horse a little house with few items but since the last update i cant play anymore on a normal level.

i found a way to still be abel to play but its getting annoying. First i need to recover my last safe fille, then i even need to demolish the house in build/byu mod only then i can loda the lot in game mod have to rebuild the hous. Whats really getting on my nerves a lot. I need to safe the lot in my gallery then get everything in my family inventory(at most every Item is already Upgradet to max) and then place everything new. T-T

What happend since the last Game Update that i cant enjoy my game anymore. after puting this online im trying to find if it is a mod or CC. The mods and CC are all up to date. 

pls help     i cant anymore T-T
