When using flame cascade cast and anywhere(open world, instance) against ennemies, the FC animation get stuck and have to wait a minute to see the character back to normal position. It is like the game is losing connection but it is not because it doesn`t kick me from the game. I saw a few bug reports and saying that it was resolved but it is not. It still happening on Ps4 and often. Please look into it. Here's the link to the bug report i created: https://dgcissuetracker.com/browse/DC-2173 Thank you.
This happens occasionally to me. Nothing else in the game will be lagging except for Flaming Cascade. It lasts until I relog or change zones.
When I see that happen, I usually find that I'm experiencing some kind of lag. Do what Shadowdragon suggests... either quit the mission and come back in or relog.
