With the change in the law, you don't have to have physical possession of the FOID as long as you have the CCL, so many leave them at home in the safe or whatever.
I'd do some more checking, to make absolutely
sure that you can't locate it, before you start down the path of replacing it. Someone else may be along with recent experience of what will happen if you report the FOID lost.
Out of curiosity how far away is your FOID renewal date?
At one time, I think
that reporting FOID as lost or stolen got the CCL revoked, and after a couple month wait for the FOID replacement, you could start the couple year appeal process to get the CCL reinstated. Hopefully it's not that bad anymore.

Illinois' FCCA is a prime example of the maxim that sufficiently advanced incompetence is indistinguishable from malice.
