Hi there, got up a little early today, so i had time to run a few tests. I actually was using the statblocks from d20pfsrd. I now switched over to those from the paizo prd . And I tried to use different stat blocks as well. I always copied the stat block over to a plain-text editor first before copying it into the Tokens GM-Notes (so it's been plain-text only all the time). When I use a different stat block (that for a goblin) it works just fine! But it seems the script doesn't like dire rats, because when using this stat block dire rat statblock from the paizo prd . It produces the following error all the time: Error: Firebase.set failed: First argument contains NaN in property 'current' at Error (<anonymous>) at Aa (/home/symbly/www/d20-api-server/node_modules/firebase/lib/firebase-node.js:9:186) at Aa (/home/symbly/www/d20-api-server/node_modules/firebase/lib/firebase-node.js:10:196) at za (/home/symbly/www/d20-api-server/node_modules/firebase/lib/firebase-node.js:8:468) at G.W.set (/home/symbly/www/d20-api-server/node_modules/firebase/lib/firebase-node.js:128:98) at createObj ( So it looks like there is something wrong with the stat block.. Just to make sure it's not me doing something wrong on my end as well thats the content of my tokens GM-Notes field is as follows: DIRE RAT CR 1/3 XP 135 N Small animal Init +3; Senses low-light vision, scent; Perception +4 DEFENSE AC 14, touch 14, flat-footed 11 (+3 Dex, +1 size) hp 5 (1d8+1) Fort +3, Ref +5, Will +1 OFFENSE Speed 40 ft., climb 20 ft., swim 20 ft.
