This is rather large issue. Sometimes the game seems to fail to load specific graphic effects etc. since I can't sometimes see shadows of the players or enemies' cloak.

The shadow issue is quite simple. I can't just see the shadows of teammates and enemies. However, the cloak works very weird. Instead of showing red tint, the enemy will sometimes blink a little bit, but that doesn't always happen. When both of those graphics bugs occur, it's impossible to see the enemy, even in situations where it would normally be easy to spot.

This has occured the most in Central Cavern but I have noticed this in other maps too.

It would be nice to see this fixed as soon as possible.

Strange, that hasn't happened to me. Or maybe I haven't noticed.
