I think this relates to this bug report. All cloaked units are completely invisible even to the player who owns them! However when I toggle shader off, then they look as they should look (transparent, but visible). Is there a way to fix this? I'm using the latest beta.
In previous beta versions it worked as it should, but in the newest it isn't. Is there any other ways to fix the problem except toggling shader off? Everything else looks much better with shaders...
