kris, you're absolutely right, by the way: advising someone to comment out a line from the script of a perfectly working table WOULD be bad advice.
But obviously this is NOT a perfectly working table!
I've had to comment out a LOT of lines to get tables to stop annoying me with stopping suddenly in mid-game, complaining about some script problem.
I don't know how to solve whatever it is they're bitching about. I also know that, evidently, what I ran across is either a rarity or something that the table works just fine without, since it's been unusual indeed when I ran them again and they spat back at me a complaint about my having taken out that line.
I know very little about scripting (though I've learned a thing or two from playing with VP, and also from listening and learning from you guys), but one thing I'm pretty sure of is that a lot of authors on here grab large pieces of script from those who have come before them, which is a nice thing, especially when they give credit where it's due...
...but in some of those cases, that script that they've thrown in piecemeal doesn't quite match up with the machine they're dealing with. It was specifically intended for a three-ball machine, and they're making a five-ball; it was meant for an add-a-ball, and they're working on a replay. It rewards replays based upon specific thousands coming up, whereas their machine eventually grants thousands in multiples, and thereby skips right past the rewards. (Want some examples? I could give some, but would prefer not doing so.)
I think probably the most frequent script problems stem from exactly that: people "borrowing" snippets of script from other tables, and us users finding out, in the end, that those snippets don't quite match up the needs of the new table perfectly. I certainly don't blame the originators, nor do I entirely blame the "borrowers," except that perhaps they didn't test their table enough to find those bugs. (Of course, I'm giving them the benefit of the doubt here, that they didn't know those bugs were there and released the table anyway!)
Still...nine times out of ten, if you comment out the offending line, it will be very rare for you to encounter that bug again. (But you WILL, eventually, of course, if you play the table enough!)
