·When releasing a sector as a vassal, if you are in the Federation and federal law allows vassals to join, the released vassal will correctly automatically sign a commercial pact upon joining the Federation. (In vanilla, when a country joins any federation, it will automatically sign a commercial pact with its members. The vassals formed by the release of sectors may have been generated directly within the federation, mistakenly bypassing the judgment of joining the federation and failing to automatically sign, and you cannot actively sign with it, resulting in a loss of production.)
