Omg that sounds awesome!  I now have zero regrets about modding fun in my game!

What do you mean?  If you trapped your sim in a dark room with no exit, your sim's fun would eventually fall past halfway?  Cause mine would not.  The motive was set to migrate up to half if it was below (+1 per hour), or migrate down to half if it was above (-7 per hour) until I changed the game files.

I didn't see the -7 or +1 in the motives.xml like you see 14.5 for bladder, but it was "DecayToZero" instead of "VariableDecayByMoodlet", so I fixed it and set the moodlet decays, so now if my sims are trapped with nothing to do their fun will eventually fall to -100 like any other motive.

So they can starve to death but have their fun be "meh."  Why doesn't that surprise me?

I found in simpe that, instead of VariableDecayByMoodlet or FixedDecay, fun's motive decay is DecayToZero.  I don't know if I'll be playing anymore until I fix this.

Thanks for the replies.

[EDIT]
Well that was easy to fix.  Now I have mine where it continues to drop below halfway until -100.

I get the theory behind it, since now negative fun means "stress" and not "boredom", but it's just too different from sims1 and sims2 for me.

Thanks again.

So, for some reason, my sims' (any and all of them, be it a new neighborhood, previous saves, moving/evicting/etc.. with and without awesomemod) fun bars migrate to halfway and then stay there.  Like, they can do fun things and it'll go up, but then back down to half, or they can mop and get it below half, but then it migrates up.

I've posted about this on the wonderful forums EA has provided, but I'm going out on a limb in hoping maybe someone here knows how to fix this?  My game's fully patched (in fact this is probably because of a patch problem).  I have LN, AMB AND WA.

I've been using Awesomemod since before the problem started, and moving all mods out of my sims folder didn't make the problem stop.  You can read mine and other threads people have posted with this problem if you want: http://forum.thesims3.com/jforum/posts/list/631924.page

I'm just looking for a way to fix this even if that means through modding.  I'm pretty rusty with modding since making objects in sims1 with codex and iff pencil, but I'm hoping maybe someone has knowledge of how moods and motives work for the game.
