fallout 3 buyers are bethseda's Q&A :flamethrower: bad bethseda
Couple points:
I kinda think it COULD have MAYBE not been an obvious issue to their QA if they were making a point to not test with any .esps in the test environment.
HOWEVER, that fact alone doesn't mean that it's an issue that's fine to not handle (I'm not suggesting that's their perspective, just saying).
This problem is different from making a patch that simply breaks mods. In practical terms, it seems to have broken the function of .esp files. That's different than mod compatibility, that's a broken program function.
But yeah it coulda gone over the heads of their testers. Perhaps those testers should, actually, use a few .esps now and then to have a chance to catch this sort of thing (and thereby prevent threads like this one in the future
).
and edit: this patch does actually contain nice things that I think must have been meant primarily for MODS. The teleporting-door-followers-issue had minimal impact if any on vanilla game (I have yet to unload my megaton door script and try it). That was a big mess for MODS. And unless I'm imagining this, I also think that followers who come through a teleporting door with you are now more spread out into the room instead of trapping the player. That's specific to MODS, there's no issue in the vanilla game because you have no more than 2 followers at a time and you don't get trapped to speak of. Like I said I'm using 1.5, I'd like to see the .esp issue fixed though, but I'm using it.
