The other night in the game that I run, I was having trouble dragging and dropping spells onto a character sheet. I'm the DM in that game. Tonight, while playing in another game, the token action for spells which pops my spellbook to the chat so that I can cast a spell stopped working. So, I tried to cast directly from the spell sheet of my 5eOGL character sheet. All that happened is my name went to chat with a blank line. I asked the DM to try and he had the same problem. The DM then noted that he was able to manipulate dynamic lighting lines on his GM layer even though they're on the dynamic lighting layer. Other players had problems casting as I did. Some on Firefox and some on Chrome. Note Vaelin and Mossy on the picture below:
