Last night we had our game, and there was some weird stuff happening
with the character sheet. We were noticing multiple 3-d dice being
rolled for single dice throws. For example a sword that's 1d8 was throwing a few d8. An axe that's 1d12 was throwing a few d12. It appeared to be doing
the actual math correctly, but my players were confused. Sometimes it
looked like the lower of two dice was being "chosen" - EXAMPLE . However, I proved that it was using the higher die just as often - EXAMPLE . This hadn't happened before with previous versions of the sheet. Also
advantage and disadvantage worked unreliably. Sometimes it worked at
first, then it stopped. We'd switch from normal to adv to disadv, reboot
the game, etc. It would work again, then it would stop. We wound up going with roll 2d20 as a stop gap. This
morning I am trying to reproduce that, but it seems to be working okay.
For absolutely certain though, it was bugging out last night. I took 15
minutes during the game and we tested it repeatedly. If it helps, I
tried with the sheet embedded in Roll20 and with it popped out of the
browser. I wonder if Roll20's servers were being crushed...
