Quoted from Krank:Its probably just huge bug and its sad that is not solved even in last update. I install LH-6 ROM yesterday. I play few games (normal mode, no Turnament) and once I noticed I collect the flashlight by Old Mine hit- hallelujah In next game (without any changes in setting) I have flashlight from beginning again.....fuck.
So, it looks like its some kind of random which is slightly stupid.
I had the same type of experience, although my Lost Mine opto was failing and I don't know if that contributed to the occurrence of the flashlight. This was with the LH-6 ROM, right after the factory reset. I had a few instances of getting flashlight award (i.e. it was not being spotted) right after the reset to factory defaults. The thing is my Lost Mine was triggering by itself so it wasn't exactly "normal" gameplay. This was happening pretty early in the game. Since fixing the Lost Mine opto I haven't seen that happen again (now the Flashlight is spotted). So, maybe its something that only happens right after reset, or maybe you can only get it if you hit the Lost Mine very soon after the first ball is in play.
So, I'm back to thinking the only way to play where it's not spotted is to put the game in Tournament Mode. The only thing is, that Lost Mine shot is so hard to hit that I'm fairly certain the spotted the Flashlight to make up for that. I rarely get the Gold Rush even when it is spotted.
