Unable to use skills or click on loot in map

Suddenly lost the ability to click on loot, open portal, checkpoint or use spells/abilities in map (was doing delirium at the time). Was still able to navigate using WASD and click on menu options. Did not resolve after dying. Attempts to use portal received "cannot use portal at this time" message. Monsters still trying to attack my character. Resolved by exiting to character screen and logging back in.
