This is a little unusual, I suppose. I was experimenting to see if I could roll different kinds of dice and keep the highest few, for instance, rolling 2d10, 3d8, and 2d4, and keeping the highest 2. Now, when I put /r 2d10+3d8+2d4k2 it only reads the k2 on the 2d4, which is appropriate. I tried /r (2d10+3d8+2d4)k2, and it rolls I believe the 3d8, but nothing else. More importantly, the dice are stuck to the screen now, and the roll does not show up in the chat box. Afterwards, any other roll made is similarly stuck and doesn't show up in the chat. I suppose this is unlikely to come up since () are not regular dice function elements and I was just experimenting, but since it basically breaks the die roller if it's done accidentally, maybe someone could look into it.
