Player Vision with multiple tokens

[Eldintux]

I seem to have a problem with players that have ownership of multiple actors (including but not exclusively familiar/minions etc). When both actors are on a scene if something changes on the scene (eg adding a new light) the player loses all vision. This only appears to happen when the scene is set to token vision. If you re-add the permission for the second actor for the player the problem disappears. Until they log in next time. There's nothing in the logs. I've tried it in a fresh world and it still happens with fresh actors (the actors don't have to be linked through minions just have the same player with ownership). I can't make it happen in 5e. If you are trying to replicate and everything appears to work, logout as the player & log back in then add an ambient light to the scene.
I have included a zip file with both the actors from the new world, not sure what else you would require

actors.zip

That sounds very much the same like my issue, except that I do get an exception in the console.
It says "This is not a registered game setting" and is caused in foundry.js::get(namespace, key), with namespace="D35E" and key="sharedVisionMode".
Callstack says it is called from token.js::_isVisionSource()
I have searched all files in D35E folder for "sharedVisionMode", but it only appears once in token.js, does not seem to be set anywhere.
I am using v0.99.1
