reasons? mistake is enough of a reason and to me seems need to fix that hundreds of popups start to pop for a mistake. Why purge should start when enabling, disabling a mod, it was not like that some few months ago. There could be a popup suggesting a manual purge instead and a new deploy, not automatic ones, at least there should be an option to choose the approach.
Anyway, hundreds or thousands of popus should not happens whatever a user makes
