No worries, more information is good. Sorry to assume you were a warm water diver.
Usually the leak is in the inflator itself, a leak in the hose would have reg hose bubbling when not attached. If it changed rather than ended, most likely the inflater mechanism on your BC needs to be cleaned and/or the Schrader valve replaced.

It was in the mechanism - the hoses themselves were technically all fine, the button was just sticking ever so slightly. We took it in and fixed it up after that dive and didn't have any further issues.
