Looks like your mod is trying to alter the window before it is created.

To reproduce:
- Have sonaxaton-resource-map-markers installed and used.
- Add tagbook mod
- load save
- instant crash

Error while running event sonaxaton-resource-map-markers::on_configuration_changed
The mod Tag Book (2.0.5) caused a non-recoverable error.
Please report this error to the mod author.

Thanks! I fix that next patch.

Work! Check update.

Thank you, it works now (but gives a large lag spike when loading the save)

Here is a link to my save, including a version of the other mod with a bugfix (a problem with pyanodon mod pack)

If you have a large number of tags from the sonaxaton mod, there will be problems. This one deletes and re-inserts all resource markers on the map each time it loads. My mod sorts and filters according to your preferences with each addition. Accordingly, each addition causes a check of the list. I guess that's the reason for the long load.

you could try to not sort on every addition/deletion, and schedule one every 10000th tick or something

This sounds more like a problem that the other mod should fix.

Most likely, I will update the sort only when the menu is open.
