I know what you mean, my first pinball is like that. It look great but every couple games or so some trouble comes up.
On my LAH:
* intermitent problem with left flipper. Fixed for now but switch may be faulty.
* Cat target need foam to stop air balls
* That damn crane gets out of adjustment every couple games or so. Anyone have a trick to prevent that?
* Tar pit lock plunger wont go down enought to release 2nd ball during mb.
* crane vuk switch stopped working during a game
Still love that game overall.
