Okay, I still seem to have the same problem as last time (I have 0 hobby hacks) and yet I"m still getting the "Sent crappy GUID" message. In addition to the "Talk about hobby" in the log, I'm now getting "Pass Along Reward Knowledge". I have no idea what the heck that means. So what's really going on?

My games are as follows: Base game (obviously), University, Open for Business, Celebration Stuff, Family Fun Stuff, Glamour Life Stuff, Seasons, Freetime, Nightlife, H&M Fashion Stuff, IKEA Home Stuff, Kitchen and Bath Stuff, and Mansion and Garden Stuff.

FYI, I have to turn on testingcheats to get the error messages because my Sims portraits go jerky. Wish I could describe it better, bu that's what happens.

Also, I'm using MATY mods and I've taken out anything that wasn't compatible (Bon Voyage, Pets and Apartment Life related) and I'm still get the jerkiness.

The error message is not consistent with the default op-code, in M&G the Lua script that throwing the error is run at node 0 of 'Social - Interaction - TEST - guid in T0 & T1 - adv adj', in your error message it's running at node 7 so you have something that's overriding that global op-code (Social - Interaction - TEST - guid in T0 & T1 - adv adj)

If you have M&G but not Apartment Life then a lot of mods were not updated for M&G and will fail to recognise it (including the CEP extras) they depend on an Apartment Life controller (usually the networking controller) to exist before checking 'game edition flags 2' those controllers are flagged to require AL so they wont exist. This does include the smarter EP check so don't use anything that depends on it.

Okay, I have no idea what you just said there.

Do you have AL OP?

All my games are listed in the first post.

Well, in that case Chris seems to have indicated the problem:
"If you have M&G but not Apartment Life then a lot of mods were not updated for M&G and will fail to recognise it (including the CEP extras) they depend on an Apartment Life controller (usually the networking controller) to exist before checking 'game edition flags 2' those controllers are flagged to require AL so they wont exist.

You have incompatible mod(s) and probably will need to perform the 50/50 dance.

You can try clearing out your logs folder, start the game and open the custom content dialogue from the game options in neighbourhood view. That will cause a fresh CustomContentObjects.txt to be created in your logs folder which will list the mods that 'Overrides Game Behavior', the problem is most likely one of them.
