Rewards claiming automatically

[napelvs]

Describe the bug This bug was a headache but after hours of investigation, I finally have an explanation.

After claiming rewards and the Metamask transaction goes through, pSTAKE will automatically claim rewards without pressing anything. This usually happens in a 6-8 minutes timeframe. Performing a "claim rewards" transaction in this timeframe, messes up the entire application and results in lost funds (tokens under "unclaimed rewards" disappear). This may also result in a pending transaction on Metamask.

Here are my addresses, it could help to verify the transactions:

• 0x6c2b8F1C4BB1501049455f1d488ADe6b42Ea2adF

NOTE: This only started happening after I have made 1900 transactions over 4 days.

To Reproduce Steps to reproduce the behaviour:

1. Go to pSTAKE application
2. Wrap some ATOM tokens
3. Stake some tokens
4. Wait a few minutes to generate pATOMs under "unclaimed rewards"
5. Press "Claim Now!" and proceed with the transaction
6. After the transaction goes through, wait for 6-8 minutes
7. pATOM tokens under "unclaimed rewards" will automatically be claimed

Expected behaviour Rewards shouldn't be claimed without the user's desire.
