on first picture u a mead cup, it was not there when i placed the ballista and cause of it i could not hit anything, the cup did stop the arrow. there is so many glitch like this now days and u miss the aim ponter so u just shoot in the ground infront og you.
Next picture is missing texture or to much. anyone has this and knows how to get it away? after getting killed by a zerg this happens why to often, also that u can se water on the ground as this texture failure before it starts raining. i have a brand new computer with gtx 1080ti card, 32gb ram and intel i7 cpu. i hav switched off shadow and water reflection and running game on high only now
