[BUG] Whole map turns gray after clicking on one of my token.

[COD3lock]

When I click on one of my token on the map, I lost sight of the map, like a layer of solid gray appears on top of it, because I can still select everything without seeing anything.

• If the vision of this token is disabled, this issue doesn't show up.
• Loading the world with the token vision disabled on this token, then enabling it again, the gray layer appears instantly. Only an "application reload" helps after this.
• The owner of the token (the player, not the GM) sees only black instead of the map, when the token vision is enabled or disabled in the map settings (same in both situations).
• "Find the culprit" module says, that this module is causing the issue.
• Reloading the application helps when this happens.

Can I see a screen shot of the gray?

Can you disable all other modules to rule out incompatibility with another module?
