It can't populate the location of the infant which leads to lag because the infant is being held at the time.  I am pretty sure the LastException file would be way more beneficial if I could post it in this forum but every time I do it gets deleted.

whenever I try and go on a date with my sim it either resets or gets stuck on the loading screen , it does the same thing if i use anothe sim from another household to ask out my main sim!

Hi NaomiAdebiyi 

Do you have any LastException files in Documents\Electronic Arts\The Sims 4 ?

- Delete the ones you have
- Trigger the error again (make sure you do this on a game with no mods/cc)
- Check if new ones are created
- If that is the case, please copy/paste the content here. You can open the file with any text editor.

Deleting the file won't fix your issue. Uploading the file is meant for troubleshooting.

So I moved my mods and was able to go on a date .

but I also got a last exception file

These are all still from a modded game.

Do you still get any on unmodded ?

Hi!
Is there any way to fix this error? 

I have all expansions, game and stuff packs and most of the kits. I play with mods, but I removed them for testing.

Last Module Called: cpp_message.py Last Function Called: SerializeToString Error message: Exception occurred while attempting to populate a repeated field: (EncodeError: Message is missing required fields: [b'accountid']), CategoryID: cpp_message:613

I keep getting this error, I was informed this is a game bug (This is an error with the EA matchmaking system, introduced with game version 1.113.) and I was advised to delete my saved family from the gallery (did not help) or that I can disable the Gallery Sims in Cupid's Corner settings (found in Game Options > Pack Settings > Lovestruck) until the error is fixed by EA. But I love that feature, I rather not turn it off. Are there anything I can do or should I just ignore this error?

I tested vanilla, and I get the same last exception:

I think I am having the same bug, but I do not have an infant. I do not remember if I had an infant when this bug first appeared in my save.

I don't think infants have anything to do with the LE. There's several threads. Not sure yet which will be the main one.

Re-opening this as it seems to be a legit LE.
