Ok, here's what I'm doing right now...
1. I'm going to the anime page for Rurouni Kenshin - Reminiscence and click on the expand-all button.
2. I select eight files for the four episodes, namely all zx and all ax releases, and add those to my mylist:
Added fid: 17131, status: unwatched, [unknown]
Added fid: 17132, status: unwatched, [unknown]
Added fid: 17133, status: unwatched, [unknown]
Added fid: 17134, status: unwatched, [unknown]
Added fid: 8803, status: unwatched, [unknown]
Added fid: 8804, status: unwatched, [unknown]
Added fid: 8805, status: unwatched, [unknown]
Added fid: 8806, status: unwatched, [unknown]
3. I go to my mylist, click on "r" and expand Rurouni Kenshin. At this time, the stats are 8/4 Eps, 0/8 viewed, the anime appears in bold black indicating that it's complete but unviewed.
4. I notice that the episodes counter is wrong which wasn't the case earlier when I had been changing SE Lain, so I'll stop this experiment now. Anyhow, the two incidents make me believe that each file that is added or deleted to the mylist increments or decrements the episodes counter, regardless of whether another file for the same episode is already there or not.
By the way, SE Lain has magically appeared on my mylist again as well. It seems that the cache was refreshed, or rather rebuilt, since a few hours ago when I posted the bug report...
Once the cache is rebuilt again, I expect that the Eps counter for Rurouni Kenshin goes back to 4/4 as well. If that happens, I'll try to reproduce the SE Lain problem - and I'm pretty sure that the same thing will happen again.
