Hey I found a bug
the shipwright glues the root part onto the vessel that has the shipwright
pretty sure this can be fixed by making the root a stack decoupler but it is kinda irritating since there is no way to detach it (that I've found)
Intresting mod
personally I will not use this as I have other mods that I think are better (free IVA and USI) that supliment this perfectly but keep working on it (if you still are)
