Yeah, that sucks
I recently had a terrible brew day where the mash bed compacted so tightly I couldn't get more than 5l of wort out at the end. When I fetched the starter (White Labs 004 Irish Ale), it had an intense smell of vomit (sour and all). Luckily, I had some dry yeast on hand (BRY-97). The end result was a single bottle of imperial stout and a 5l carboy of still fermenting oaked Brett Imperial Stout.
I recently had the one bottle of Imperial Stout: it tasted heavenly. It's impossible to tell if that made me sad - seeing how it was the only bottle of that beer - or happy that it wasn't all for nothing.
In retrospect, I'm not entirely sure what was going on with the starter. The smell coming out of these yeast vials or starter packs often isn't entirely pleasing. But it's so hard to take a risk at that point - so maybe you actually did just the right thing. Without even knowing it.
