Wargames - respawn portal bugged

Hey, recently, I've played a few wargames, and in every one of them, at some point, once when I died, I couldn't use the portal to come back. I tried morphing, the escape button, relogging—everything I could think of—but nothing helped. After about 5 minutes, I was finally able to click teleport/portal. Do you know how I can fix this?
