Rolling lower than possible

[BabyCthulhu]

I have recently seen this rolls (http://www.giantitp.com/forums/showsinglepost.php?p=21653058&postcount=117) on one of the games I'm playing.

And I can't understand how that could have happened. Can anyone please tell me?
How can you roll 1d8+1 and get a 1? The post is not edited, and when quoting it it shows the typical [roll0] text.
Is this a known issue? I couldn't find any info about it.

That post likely used the [rollv] tag instead of [roll]. [rollv] Shows each individual die, not the total result, so things such as a numerical bonus to the roll are ignored. The numbers shown in that post are therefore the "natural" results of the dice, and the bonuses should be added to them to determine the result.

Ohhh, I see! Thank you!
