looking into the simulations failure atm

[skyargos]

ibc-go v3.1.0 api-breaking

• (transfer) #675 Transfer NewKeeper now takes in an ICS4Wrapper. The ICS4Wrapper may be the IBC Channel Keeper when ICS20 is not used in a middleware stack. The ICS4Wrapper is required for applications wishing to connect middleware to ICS20.

I will add this.

Isn't that changelog for v3.1.0? we're upgrading to v3.0.0

[xiumingdou]

The go.mod shows 3.1.0

Modification from 'github.com/cosmos/cosmos-sdk/simapp' to 'github.com/cosmos/ibc-go/v3/testing/simapp':

1. ModuleBasics in the simapp of cosmosSDK does not contain ica.
2. The 27-interchain-accounts module of ibc-go does not implement the AppModuleSimulation interface.
3. The simulation initialization cannot be completed in AppStateRandomizedFn of cosmosSDK, so use ibc-go instead. genesisState simManager
