Some Items seem to have no option to pick them up when they are on a pedastal or somthing similar. Here is one example that i came across. No matter what i tried I couldn't get the option to try and pick it up.
Edit: Found another bug. The mutaion that allows you to teleport instead of roll (while great and feels really fun) if done in the direction of a ramp telports you behind it and generally leads to falling into the abyss. If you teleport in the direction of a worl wall that you shouldn't be able to teleport through same effect. I had times were trying to avoid an enemy i tellport through a rock wall and take damage from falling off the map.
