I was recently adjusting the bridge height on my schecter c1 when i realised that the washer which surrounds one of the bridge screws has went down into the guitar where the screw goes. It doesnt seem to have made the bridge loose etc so is the washer just for cosmetic purposes or will this cause a problem?

I don't want to look like an idiot taking it to my local guitar tech.
Forgot to add it's just one of the washers and not both of them.

Any advice would be appreciated.
