unsafe_payAllSui to same address

Hi there, I’ve tried to build a transaction using unsafe_payAllSui using a same address as the signer and recipient. I did this to try to merge multiple (more than 2) coin objects into one instead of using unsafe_mergeCoins which can only merge 2 coins at a time.

I thought it should reduce the SUI balance by the amount of the gas fee. But instead it added the gas fee amount to the balance.

I want to confirm, is this a bug or as expected?

This is the tx that I used:
7RpPsey5HGp93LszXRhwWH7vrZWnCQpkrh4zKs5GmoP3

Update:
The transactionBlockResponse:

No, I haven’t. Maybe I’ll try to reproduce it to check the result again.

Sorry, I can’t find the live chat button. Where can I find it?

Yeah thanks for the heads up. I opened the link and it showed unsafe site warning.
