Shadow Cave 3 Bosses Do Not Spawn

[Smartress]

I am not sure this issue has been raised before, so far I have played Shadow Cave 3 half dozen times, I always ended up with 4 mobs left, but cannot locate them anywhere on the map.

It is frankly annoying.

I cant stand that glitch< it happens without fail every time I have played it as well.
