It's different from not being locked on to a target, since it'll immediately say "missed" if the glitch happened

There's also the one where heavy artillery is counted as a naval target unless it is obviously at a high altitude (even the artillery at Alps, which is fairly higher up from sea level, is counted as a naval target). That one will probably be fixed sooner than this new bug.
