"Detected out-of-range float (inf or nan) when writing JSON file"

Can't be good right?

I get this message whenever i try to save a specific patch i'm working on. It saves just fine and i haven't encountered any other problems but i'd like to know if this will persist and/or have implications later on because i plan to expand this patch quite a bit.

Thanks,
FRid

i'm guessing i should start over just to be sure :(
