[1.4.5] Addon-dev suddenly generating a new number?

[Dracos]

http://te4.org/games/addons/tome/improved-restauto - for this, I suddenly (a couple of days ago) started having steam uploads go weird. You can see all of the versions there but what happened is:

1)Sometime on sunday, it decided that the pub-id of the addon had changed from 440747756 to 641448308. Because of this, when I tried to upload latest fixes, it apparently went and created a new addon. Very weird, especially since the te4 site got the right one.
2)To get it to upload correctly, I eventually just hardcoded in the addon-dev the right value, so fixed addon is up where it should be... but I have no idea as of yet why it would change. It has to be the input to the below function changing, but all I did in that timeframe was hop back and forth between Embers being enabled and disabled (to make sure I'd fixed it with it disabled).

core.profile.pushOrder(table.serialize{o="AddonAuthoring", suborder="check_steam_pubid",
for_module = game.__mod_info.short_name,
short_name = add.short_name,
version = add.version,
md5 = fmd5,
})

The te4.org site reference for the addon definitely still has the right pubid stored in it. If that makes a difference?
