Okay guys, I have some papyrus logs from one of my testers.

Now, these are peppered all over:

[10/25/2012 - 11:39:50AM] warning: Unable to get type SF_FSMQ04ExplodeBorvald_01042C60 referenced by the save game.

Does that mean that he's using a dirty save? His save should have never seen my mod before, so why is it getting an error that it cant find one of my old scripts? (Before I renamed them all to have the same FSKR prefix)

So is that why this isn't working? It's a dirty save issue? He loaded his save and tried and got these errors. Then he loaded in STRAIGHT from the main menu via coc, and it worked. Are my testers just being silly and somehow getting their saves dirtied up? (Even though they swear they're clean...?)

I guess it means so, indeed. I fail to see how a clean save could hold a reference to one of your old mods.
Unless you're still referencing it somewhere in your mod?

No I swapped out every single instance of the old scripts and renamed absolutely everything.

The weird thing is my testers swear the saves are clean. From before the mod was even activated. I guess they accidently 'polluted' them at some point though, which explains this thing's randomness?

Are you distributing your beta as loose files, or a BSA? Either way, my users tell me lots of stuff in bug reports, and alarmingly what they say is not true (though ignorance is usually the culprit, not stupidity or maliciousness). Just look at what the data is objectively telling you.

I used loose files until about 2 versions ago, now it's a BSA. And yeah, I've asked other testers to verify with gurentee'd clean saves.

Make extra sure that your users have removed all of your loose script files, that may be a source of problems down the road. Perhaps not this one, but still.

Yeah I told them many times when releasing the first BSA one. I'll say again this time.
