My character used advanced battlefield training on himself to cantrip into the new round, my opponent claimed he couldnt do any actions afterwards despite his clock running. He did time out since he wouldnt reload in time.
Just tried this on test server. Both Advanced Battlefield Training and Battlefield Training freeze on the opponent's screen after self targeting. Reloading fixes it but this is still one heck of an exploitable bug.
I've patched a fix in for this on the test server and I'll migrate it to live a bit later today. Thanks for finding!
I've patched the live server. There does seem to be an issue with the new data propagating out via Cloudfront, so I'll check again tomorrow. If it's not fixed properly I'll have to deploy a full new build with a new version number.
Unfortunately it looks like I have to deploy a new build to fix this properly. Will happen later today.
