The beta test is meant to find issues like this so that our developers can work on them before the new engine is implemented the game runs as smoothly as possible. Remember to use the appropriate form when reporting the bugs: http://plrm.me/spartabeta 

I have so far had to report about six glitches. Coordinate bars missing at edges of map.Copy to clipboard not working in messages but does in chat. Towers not showing as repaired when repairing friends towers. Coalition mission only shows 4 steps/rewards instead of 5. Friend list at base of screen is wrong way round, shows low lvl to high not high to low. Plus it does not run as smoothly as it does when I run Avant Browser. It does not bode well for using Chrome, but I will keep trying.
