Collectible Card Game Headquarters

I can't see the arrows that indicate when a creature is blocking another creature or when a spell or permanent is targeting another permanent. Please help! Is very stressful to play like that. What should I do to fix this?

Is this the mobile app or the desktop application? Have you checked your settings to make sure you didn't accidentally turn off arrows?

I've seen this on the desktop app. It has to do with the UI cache not updating immediately when attackers or blockers are declared. So your left with a declare maybe being declared, but the UI not updating to show the arrows (or the combat panel either) so it's unclear if anything happens. The same thing occassionally happens when attacking Planeswalkers.

Ok, And how can I fix it?

I'm using Windows 7 Home Premium 32bits
