## Description

Some tests are still failing, eg: https://github.com/cosmos/cosmos-sdk/runs/4350294236?check_suite_focus=true
With message: 

> go: updates to go.mod needed, disabled by -mod=readonly; to update it:
>	go mod tidy
> test return:  1

Also, when using the latest version it cleanups the go mod.
