A bug with Halfeling's luck

Hi everyone ! I had a little bug on during my last party of D&D 5e (2014) on Roll20, one of my player that play an Halfeling make a Strength test and got a natural 1. 'Cause he's an halfeling and the halfeling luck is check on the character sheet, the dice should have be automatically roll again, but instead the result show a 10 on the dice, like the Reliable Talent of a rogue. This is normal, can I juste be fool, or there is a bug on my player's sheet ?

Hi Kawazam,  Can you supply a screenshot of the roll with you hovering over the roll?

And on the 3D dice that be throw, everyone see a 1.

Kawazam said: And on the 3D dice that be throw, everyone see a 1. What I am seeing on my end is the first 3d d20 is a 1, the second 3d d20 is the reroll, and in the instance of your screenshot should have been a 10.  Is that not what you are seeing?  In any case, based on your screenshot it appears to be working correctly, even if the second 3d d20 is not rolling.

Yeah this is the thing actually, the second 3D dice never roll and the result appear like this in the chat. Maybe the second dice never roll in 3D but had a result of 10 and this is why it's looking like a Reliable Talent.

Mind PMing me an invite to your game? I'd like to come and see if I can replicate it there.
