While trying to reroll more than a single die roll per equation, using < or > will cause the output text to fail. It's easy enough to test. /r 2d10ro<2 + 3d6ro<1 the output rolls correctly, but the display is "rolling 2d10ro<2 + 3d6ro" /r 2d10ro<3 + 3d6ro>5 works fine because it is a < & > /r 2d10ro<3 + 3d10ro<6 + 2d6ro>5 is where it gets weird. Output is " rolling 2d10ro<3 + 3d10ro5" It rolled correctly, but completely split the output and reformed it, removing everything between the 2nd < and the >
