I found this bug while trying to see if I could see he status of a transaction that was submitted to the host chain from the controller chain. Would love to get something like a TX hash that I can use to see if my TX failed on the host chain. Or query the host chain with my account to see a list of transactions?

thanks @okwme! I opened #666 which fixes the issue (but you'll need to restart your chain with the updated binary)

As far as seeing the status of a tx. The ICA auth module will receive the acknowledgement result in OnAcknowledgement, it could log the result there or we can ensure the packet sequence used to send the transaction is returned to the user. Then you could query for the acknowledgement on the host chain. We could add a command to ica which parses the acknowledgement result
