# v9.0.2 pre-release testing
`consumer-removal` bug fix
A new version of Gaia will be released to fix the bug where a consumer chain is stopped immediately after a `consumer-removal` proposal passes, even if the `stop_time` has not been reached.
## Testing
v9.0.2 will be ready for release after these checks are completed:
- [X] Replicate bug in local testnet
- [X] Confirm bug is fixed in commit [b0b42fce13d92814aec786d575a410f6d98b7ee9](https://github.com/cosmos/gaia/commit/b0b42fce13d92814aec786d575a410f6d98b7ee9)
- [X] Confirm commit is not consensus-breaking with respect to v9.0.1
Four validators (each one of them with 25% voting power) were started with v9.0.1, and two of them upgraded to the new version.
```

curl -s http://rs-test.stg.earthball.xyz:25033/abci_info | jq -r '.result.response.version'
release/v9.0.x-b0b42fce13d92814aec786d575a410f6d98b7ee9
```
All four validators continue to create blocks after upgrading:
```
Proposer blocks from 2305 to 2404
val4: 25
val1: 25
val2: 25
val3: 25
```
Start new consumer chain and submit a `consumer-removal` proposal from a non-upgraded node

- [x] Upgrade RS testnet to v9.0.2-rc0
- [X] Launch new consumer chain in RS testnet
- [X] Pass consumer-removal proposal with a stop_time set at least two hours in the future: https://explorer.rs-testnet.polypore.xyz/provider/gov/15
- [X] The consumer chain stops at `stop_time` specified in proposal.
