Failed to perform multisig keys exchange: Failed to derive public key

[redox473]

This happen every time I do second round of exchange_multisig_keys for 2/3. Every time i do it perfectly like documentation, passing in correct order.

I do prepare_multisig.
I do make_multisig [info1, info2], make_multisig [info1, info3] etc like they do in docs.
i do "exchange_multisig_keys info1 info2" etc with info from last command.

then i do "exchange_multisig_keys info1 info3" etc with info from last command.

It works with first wallet that does the command, so long as wallet hasnt been closed after first exchange, else it fails like the others. All respond with : Failed to perform multisig keys exchange: Failed to derive public key

Could this be because im doing these back-to-back-to-back?? I perform the make_multisig for the 3rd wallet, then immediately proceed to exchange_multisig_keys, without closing the wallet or refreshing it. Is a timeout required? I will keep testing. 2/2 work fine.
