Skill Rolls cause on Error

[Grundole]

We are getting error code when we make skill rolls with PCs or NPCs.

[7/12/2026 8:31:54 PM] [ERROR] Handler error: [string "illahad-TnDifference:..pts/TnDifference.lua"]:138: attempt to call field 'onRollTNDOrig' (a nil value)

Is there something we can fix?

That specifically looks like an error from an extension; as that code doesn't exist in any of the built-in rulesets.

Try disabling the extension that looks something like "illahad-TnDifference".

That's for illahad's TN-Difference (https://forge.fantasygrounds.com/shop/items/1405/view), it was last updated (https://www.fantasygrounds.com/forums/showthread.php?79309-Extension-Highlight-particularly-good-or-bad-rolls&p=763221&viewfull=1#post763221) about 67 days ago.

Ok, thanks we will disable that extension.
