Here’s a gif to show the problem.
Water field goes down. Half a second later the blue ring disappears. 3 seconds later I successfully blast a completely invisible field.
Once again, this is a huge issue when you’re reliant on water fields for survival.
It happens with fields cast by your allies (not your own) and gets more frequent when there’s a lot of stuff going on. It started when the new colored indicator rings were introduced in the spring update.
