When I ran a charcter update in ArmorySync, I got a php error,

PHP Errors
addons\siggen\inc\update_hook.php
Notice line 127: Trying to get property of non-object

on every update.

Line 127 is, if( $update->textmode == false )
Any clue?

Edit: I am happy to report, that the signatures did update when ArmorySync ran, and they do show, albeit very small, in the notes.

Armory Sync doesn't initialize the update class as $update
And SigGen detects $update->textmode to see if the current upload is being performed by UniUploader

I guess I could add in a check to see if $update is an object first
