L5R Dice problem

I've been trying to make some macros for an L5R game I am in, and have found them through the dice reference and these forums. Here's an example. /roll 5d10k3!! This rolls five d10s, keeps 3, and has compounding explosions. The problem is when I try to add emphasis to the roll (reroll all 1's once) /roll 5d10k3!!ro I was hoping that this would make exploding dice reroll on 1's as well, but it appears that when a 1 is rolled off of an explosion, the entire roll is discarded and rerolled. If a 10 is rolled and its explosion is a 1, what results is an unused 11 that is rerolled. Is there a way I can correct this, or is it not possible in the current coding?

I don't believe what you want is possible currently.  Let me see if I can spell out what you're saying you want for behavior: Reroll 1s once:  A d10 comes up a 1 and is replaced by another roll which might be a 1, which then results in the value 1 Reroll each exploded die one time:  A d10 comes up a 10, and another d10 is rolled and comes up a 1, but is rerolled to another 1, and ends up as 11 You can get the first 1 rerolled with the ro specifier, or all 1s rerolled with the r specifier, but there isn't a specifier for rerolling the first 1 on a per die basis for exploding as I believe an exploding die is still treated as a single die, regardless of how many times it explodes.

OK, that makes sense. Do you have any explanation for why I'm having unused 11's and 21's that are being rerolled like 1's?
