When I was putting my airlock in my fermenation bucket the darn thing popped thru into the pitched wort. I can not find the little bugger.. Everything was cleaned with StarSan,, will this cause an issue with the brew??
Leave it and it'll be fine until you bottle or rack to secondary.
Wrap some Starsanned (is that a word?) tinfoil around the business end of your airlock so it'll go in the hole for now and pick up a small drilled stopper that'll fit in the hole next time you can get to the LHBS.
