Sorry Narf,
I mis-sread your post - oops - caused by FPSC giving me major headaches too - trying to post and work at the same dont work - like FPSC.
No then I would not know why - FPSC can be very erratic. I get the same problem with door entities - same door - works here - dont work there.
Its not possible to work out why it does so, me of these things as its completely illogical.
At the moment FPSC is destroying completely a level I have been working on for 6 months for who knows what reason? - just becauuse it does not like me adding something more to the level.
Cheers
