Doesn't seem to work in Foundry v9.x

Here's the error:

Uncaught (in promise) A: Error detected in module Group Initiative. It is likely this module has not been updated for FVTT Version 9.

This is *not* a libWrapper bug.

That's weird, I'm running it on 9 (9.242) myself with no issues on Roll NPC or Roll All. For interest sake, what happens when you run it with just Group Initiative and libWrapper?

EDIT Also, when does this error happen exactly and is there no earlier error?

[vtt-lair]

It could be that you have another module that is also overriding the roll buttons and that could be causing my override not to be created.

The following module might also override:

• Mob Attack Tool - (I believe they have an implementation of group initiative that was done when this module was not being maintained before I took it over. This can be flagged in it's settings though)

[geoidesic]

Ok, yes. You're right it is Mob Attack Tool. The settings you speak of for Mob Attack Tool don't help. Mob Attack Tool is completely broken and is indeed what is breaking the initiative rolls – I tried it on it's own with no other modules and it still breaks the initiative roll.

For you module, what doesn't work is group by name, which is a pity but not a deal breaker.

[vtt-lair]

Yeah, I've created a setting for group name and flagged it as experimental. It was acting up too much and giving a lot of issues. So I disabled it by default while I try and refactor the code.
