The guild leaders note is always 0, therefore every table shows up-to-date, even if they aren't. Deleting the note and broadcasting changes it to 0 again. Manually setting it to a 10 digit number and broadcasting again sets it to 0.

There was a change in how the addon stored the seed in the leaders note. It should only be a one time thing as it was to allow more flexibility with the note (leader can now keep a note with the seed appended to it rather than it encompassing his entire note).

Do you have the most recent version? 1.4.12. Make sure to update as it would be posting the note in a {MonDKP=#############} format. Nothing in the new version should be setting the note to 0.

The addon seems to not be able to write notes at all.

I created a new guild and created a new dkp table and manually edited the guild masters note to {MonDKP=0000000000} and it showed up-to-date. Broadcasting did not change the note. When changing it to {MonDKP=0000000001} it showed out-of-date.
Using the original dkp table, no matter what is in the GM note is, the addons always shows up-to-date.

I tried broadcasting the table, as officer and gm, when the note was empty, "0", "{MonDKP=0000000000}" and "{MonDKP=0000000001}". Non of them resulted in a changed note. The officers have the permission to edit notes.

Testing was done on the Classic Client.

Broadcasting would not update the note. Only modifications to the table actually change the note (the seed is to keep track of the most recent changes made). I would delete your note entirely and then make a modification then undo it. Give yourself 1 DKP, for example, and then go to the DKP history tab and right click that entry and delete it. It should update the note with a valid seed.

I used the version 1.4.11. The new 1.4.12 still keeps just a "0" in the officers note. Replacing it with {MonDKP=1000000001} and broadcasting still results in a "0".

As seen here, the note is changed instant, but if edited manually stays. I will check if any other addon from my officers are interfering.

In fact it was an out of date version of your addon. The addon is not downward compatible.

Seems like it is some officers addon, because its workes on the empty test guild.
I will update as soon as I find the bad addon.

Thanks for helping me troubleshoot.

Have all officers update their addon as it may be a conflict with how the addon used to handle the note.
