Yeah, I updated both WW and Basemental. Those two were one of the first ones I did (along with MCCC.) I have a WhickedWhims Exception and more than one last exceptions but I think the most recent one of those was because I didn't have WW installed when I had tested out your mod independent of any other mod in the folder. However, I'm not sure how to read last exceptions so I could be completely wrong. But even with WW installed (and updated), I still couldn't load into any of my families.
I can try again with your mod installed (and WW) to get a more recent one if you would like to take a look.
Hmmmm... The last exceptions will be very useful in understanding what is happening with your game Try deleting the last exception files and then starting up the game again to see if new ones are generated, and then send those to me by embedding the Last Exceptions (from all sources (WW, mine, base game's) into a reply to this message.
Sorry for the late reply, busy week at work. I haven't had the chance to get back into the game until now.
I started the game up again and tried loading into a family, yet the same thing happened (stuck on the loading screen.) The only mods I had installed at the time was your mod, Wicked Whims, and MC Command Center. However, no last exceptions were generated this time.
I'll attach the whicked whims exception from before I deleted the last exceptions and and the last exception from prior to deletion that mentions your mod (though I think that one is because I didn't have whicked whims installed at the time. Not positive though.) It's the only last exception from before that mentions your mod.
Edit: Oops, there is another last exception that mentions your mod from before deleting them but I think it's the same deal as the other one. I've attached that one too.
