Can't run composer update after adding alchemy/zippy

[NicTorgersen]

Update:
Seems to be incompatibility with Laravel 8 that is the issue.

I just spent some time debugging an issue when running composer update within a Laravel-project and found that zippy causes "Something's changed, looking at all rules again" with unlimited passes.

I removed zippy from my required list of packages and composer update ran smoothly.

I could safely remove the package as we haven't started using it quite yet.

Is this your end or my end causing this issue?
