Can Devs alert an author when a MA arc is invalid?
You should never have to unpublish an arc unless it was suspended due to complaints.
The only time you have to unpublish is when you want to put another arc in the 3 slots you have, or that the arc is not in a playable state and you don't want it played (publishable but not considered to be playable).
You can always edit your arc after it is published and as long as there are no errors, republish it and it will keep its arc ID and ratings.
Your original premise is valid though. Arcs that are rendered non-playable should be flagged so the author can fix the problems quickly.
Yeah that last patch was a killer. Not only that but there was apparently an unintentional reduction of NPC descriptions to 300 characters that has caused many an arc to be unplayable. Would be nice if there was a grace period for any changes they make not to take place in published arcs for a while, kind of like what happens with costumes fixes that don't get applied until you visit the tailor.
For the last two weeks or so, I've been pumping some heavy publicity into my arc on different websites and getting no response from it. A bit distraught, I decided to play it this morning to see if there was any glaring holes or mistakes I could change to make it more appealing...
Well, I click 'Play' and nothing happens. Hm. That's odd. I click it again. Nothing. I try starting another arc, that works fine. Well, long story short, one of the many recent patches killed my MA arc. Not only was it unplayable, it was un-editable! So for the last couple weeks, I've been sending people the arc ID of a dead arc. Wonderful.
On top of that, I was forced to unpublish the arc, losing the arc ID. I was at least happy to see I had a fairly recent backup of the arc that I was able to edit, fix, and re-publish. Again, resetting my decent rating to zero (and again, losing my double digit rating count -- second time on this arc).
So my question to any Dev that might stumble upon this thread... Is there any way to alert authors that a patch has rendered their arc invalid? It turns out I was using an animation that was removed and bam, dead arc. I use tons of animations! Sure, only about half of them work, but that's really something more I'm hoping will start working when you get it fixed, not kill my arc when you remove it. Even an automated e-mail saying one of our arcs have been effected would allow us to go and try it. Possible?
And since I'm here and back to zero, check out the arc in my sig... It's a RP heavy arc, good story, *sigh*... it's solable. Hopefully it will still be there
