wrong Block.Header.LastResultsHash

[gitmewai]

We are setting up a new terra 2.0 node under pisco-1 testnet using the latest terrad v2.1.4. We used the snapshot from https://snapshots.synergynodes.com/terra_v2_testnet/terra_v2_1749961.tar.lz4 to sync the node.

The block started syncing from 1749961 and up to 1755427. Then the following error is observed:

Our questions:

1. Is v2.1.4 supported on pisco-1? Or which latest version should be used on pisco-1 testnet?
2. Is there any hardfork at v2.1.4 on phoenix-1 mainnet? (However, we cannot test the upgrade with the same binary on pisco-1 testnet first)
3. What is the plan on using single binary across pisco-1 and phoenix-1 networks?

Thanks!

pisco-1 version is presently v2.2.0
A governance proposal is being created to upgrade phoenix-1 to the same release version (v2.2.0)
