Hi PaQ,

Did you possibly re-install MoI at some point not too long ago?

There is a bug in the way "Avoid smaller than" is handled in MoI v1, remember we discussed this before here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=1536.1
http://moi3d.com/forum/index.php?webtag=MOI&msg=1536.23

I sent you a patch that fixed that up, are you possibly running a new installation without the patch in place?

If that's not the case, can you please post the model file so I can test with the same exact data over here?
