Have you read the changelog?
Mark if read.

Please describe the bug.
Cannot change color in other addons. Get a bug error. Sexymap and weakauras both give errors if bagnon is enabled.

Please describe how to reproduce it.
Have bagnon and weakauras enabled only. Import https://wago.io/9h1Vqjhbi. Open weakauras and under display tab try and change text color. Works fine if bagnon is disabled.

or

install sexymap and bagnon only. In sexymap options go to clock or coordiantes and try and change background or border color.

The issue seems to be a shared library in Ace called color picker.

Any Screenshots?
