Well, actually i think i have now fixed it. What happened last night was that i was running a campaign WITHOUT character sheets, just using the stat blocks and values and calling data from those in the macros i had set up. It was the first time id used these macros since character sheets became live. Anything calling to any of that data simply didnt work, no errors, but no dice rolls, weird. A mentor who was playing said himself it looks broken. So, this morning i added the 13th age character sheet and had to trawl through the code to find what the guy had called the fields where the data i wanted resided, what a round about way of doing it, since some of the calculated values did not appear under the abilities tab automatically. Anyway, it all hopefully seems sorted now. I couldnt fix the original issue. I think my friend is going to raise it in the mentor forum.
