[resolved] 6.3 beta 1 Bug: Multiple items purchased quickly don't index

I purchased three free books, in three separate transactions, a minute apart. I purchased these whilst Logos was already indexing an earlier update. 6.3 beta 1 couldn't cope.

Here's what happened:

1. The indexing of my first purchase appeared stuck on 0%. After the initial indexing completed (from the earlier update), a second batch of indexing began. This turned out to be for my first purchase. The yellow exclamation marked stayed on 0% for a very long time, and the tooltip in the system tray just said "Logos is indexing", without giving a percentage. It's possible that right at the end it moved on (I'd given up looking), but it was at zero for a long time. Indexing of this first resource was successful, though.
2. The second and third purchases never indexed at all. They were discovered and added to my library, but not indexed. I have several warnings in my indexer log for both resources: "Resource of type logos could not be found at location". Here's the log: 4857.LogosIndexer.log, and the Logos log: 3683.Logos.log. I know it didn't index because I tried searching for the word "the" in those resources, and got zero results.
3. Restarting logos didn't trigger the indexing of those two extra resources, and they remain unindexed in my library.
4. Because the indexer the indexer restarted a few times in quick succession, I lost the first indexing log.

For reference, the three purchases were:

• LLS:22.0.1 (indexed successfully)
• LLS:NTOUTL5YR (failed)
• LLS:DAFYOMI13 (failed)
