After all this time mining with an anky is still a very hit and miss affair. In the blue zone trying to get metal is buggy but bearable. There are collision issues with the large clam shaped mushrooms if they are near your anky when trying to farm metal, which can be resolved by headbutting the mushroom first. However, if you go further down to try and get red crystal with an anky you get the same issues without the mushrooms. I believe it's either the spiked plants or those small org poly plants that are causing the collision issues and preventing many of the red crystals from being mined by an Anky until you find the sweet spot to hit it from, if you ever do.
Anybody found a workaround for this neglected bug?
