Error: Firebase.update failed: First argument contains NaN in property 'rotation'

I'm getting this error: Error: Firebase.update failed: First argument contains NaN in property 'rotation' Error: Firebase.update failed: First argument contains NaN in property 'rotation' at Ba (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:9:186) at Ba (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:10:207) at Aa (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:8:462) at Ea (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:10:403) at J.update (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:146:318) at TrackedObj._doSave (/home/node/d20-api-server/api.js:905:27) at Timeout.later [as _onTimeout] (/home/node/d20-api-server/node_modules/underscore/underscore-umd.js:1153:39) at listOnTimeout (internal/timers.js:549:17) at processTimers (internal/timers.js:492:7) I've disabled every script except Combat Master (Latest v2.45), so I assume that's what's causing the problem, but that's also one of the scripts that I use the most. How do I find what has an NaN in 'rotation'?

If needed, here is game link:&nbsp;<a href="https://app.roll20.net/campaigns/details/7083971/a-tale-of-dragons" rel="nofollow">https://app.roll20.net/campaigns/details/7083971/a-tale-of-dragons</a>

Looks like the error happens after: "Get or Create Marker" "Change Marker"

You have to upgrade to the latest version of Combat Master directly from the Git repository. See the Combat Master thread in the API forum for details.&nbsp;
