Hi there,

yesterday it happened twice to me that my client's video freezed (total game freezed) as I was recasting the Arcanist portal skill (not morphed, based portal skill still levelling) "at the moment the 1st cast ran out".

Like:
Cast portal, move through and teleport to the other portal.
Then move back though the other portal to the first.

The CD timer counts down and as soon as the timer is 0 I casted another portal: At this moment the whole client freezed and I was only able to end the game via task manager then.
I could not repeat this in all cases but at least 2 times.

All I found out so far is that you will have to have other arcanist skills with effects, like the big green ground buff circle, or the beam, active as well. So maybe related to "many effects shown at the same time"? Only a guess.

There is no consitent way to rebuild that bug/freeze but other friends told me they had similar issues already.
I also tried this with all addons disabled so this should not be any addon issue.
