This seems to happen everytime i try to save the file
hopefully there is a way to fix this?

I have a feeling this is one of the problems i am having
while making/meshing new files?
even though the package seems to come with this file in it when extracting the pastry file
it may be what is corrupting my new file?
hopefully it is not a maxis problem and it can be corrected with SimPe?

This is in the Objects02 files in the Sims2 not University

have you tried changing the file name to something shorter? When extracting that's just the filename you see on disk, it's not changing anything in the file data itself.

Sorry a bit late but just to let you know i had already grabbed the file from an older version of simpe
seems the file extension in the newer version wouldnt let me grab it but ill remember your trick next time :)
