I've pushed here changes needed by https://github.com/mlabs-haskell/nft-marketplace/pull/231 without creating a new PR, this should all we need in this repository for Seabug deployment.

@samuelWilliams99 @rynoV so can we merge this?

[samuelWilliams99]

I believe so, but lets prehaps wait on Calum here

@aciceri let's hold off for now, I may need to update the CTL revision again as changes were requested on my CTL PR. I'll let you know once my PR is merged, then we can merge this. For now though this version should work to fix the deployment.

Hey @aciceri, we should be good to merge whenever. I also pushed another commit to calum/updates on seabug to update the submodule versions.
