I have been playing warptorio 2 with the BZ modpack (after fixing some issues with ore generation in warptorio) and I am now looking at maybe trying it with this expansion. Unfortunately I can immediately see some compatibility issues since BZ locks electronic circuits behind research so I can't repair the lab.
I don't expect a fix for an arbitrary modpack (especially since warptorio itself does not work out of the box with it), however I am interested and should be able to fix this myself. However, without a repository to contribute back to that leaves me with having to download the mod from the portal and hack/fork it separately.
I'd be happy to contribute changes back if that is desired and possible but depending on how I far might take this (I'd need to tweak warptorio itself as well I believe) it might be better to fork it regardless. Either way I wanted to keep you informed.
