Nah, it definitely was paralysis, as you could potion yourself indefinitely and still not be able to move. Or even gate yourself to the nearest portal to escape death, but still be paralyzed there in town while not being subject to any stun attack.
Anyway, I have played for another 7 hours and have yet to experience the paralysis again. I experienced a number of changes, but others will have to confirm if they see results as well.
1) I disabled hardware mouse cursor in the menu settings. 2) I finally chose a weapon specialization skill, which elevated my base attack speed dramatically. Went back to polearms, as I experienced the same bug with the warhammer. From time to time the same 3 skill combo (was only 2 skill combo before) often fails to complete beyond the first skill, but I never see a paralysis again. (edit: remembered a nice trick with holding Ctrl and right-click will help every skill in the combo to activate most of the time) 3) One time (before these other changes) I was able to get out of it by deactivating the active buff (Grim Resilience) and leaping out of it with Belligerent Vault.
I am playing with the CM 160 patch, extra textures resources, the font patch, fog mod, and camera tweaks. And can anyone tell me how to edit a previous post?
