I was told to wait until a new release to test a supposed fix. I now am running Ovale 90031 (/ovale version). Build is the same as reported last time. I had an errant start (hitting Ctrl-1 rather than 1 to start the flow). It starts off well enough, with some spell transition, but as you watch the video, you will see me fall into doing nothing but spamming Wrath.

Here is a link to the video (in my dropbox)

As always if you need more information, you need but ask.
