Different hud behavior around holocubes
So before the patch holocubes could be spotted by red mark on crosshair and by character automatically rising sword in a lunge distance. Holocubes are classified as traps and this behavior fits it.
Now there's no crosshair red mark, no sword rising and spotting holocubes is trickier task than before. Especially with perfect picture mod.
I'm not against that solution but I didn't find anything about that in patchnotes, I don't know if it's intended thing or not. So just in case there's the report.
