Thanks for the suggestions.
When I encountered this I spammed visual distance upgrades as fast as I could. Like I said, I was trying to learn the Substrate.
I'm not talking about radar seeing around terrain. What I was saying is I should be able to see up a hill and not behind it. There might have been a plateau there to hide behind. IDK. It's a feature not a bug?
I'll try aircraft next. If I encounter my original issue again I'll try to capture it and post it in this thread.
I do love this game. I'm a big RTS fan from the era of Orcs vs Humans (which became the Warcraft series), C&C and Homeworld. Ashes is becoming one of the best.
