[Unity 3.4] - layer + matrix collision not kept with package ?

Hi dear unity geek XD..

ok well something till now never really spotted , as I am using asset server all time, but it seem that when exporting package >

1 - Layer name are not kept, gameObject seem to keep track of them but blank name, not the worst issue tho
2 - Matrix collision layer if set reset to default with built-in layer of course.

I just wonder if this may go through a bug case issue or ...


as i said I am not using package so much but right now i had to to share project , and well this issue is a bit unfortunate

would like just to have confirmation that it is an known issue , if this is something that can be fixed or not blablabla and if i should annoy UT with a bug report on this or they already get their pace about it ^^.

thanks !
