Vanilla Extended Mod v0.01 Release! -Does not work with latest patch-

[Megas Methuselah]

Do the minor factions still have the bug issues (eg: crashing when a faction emerges)?

They never did.

But campaigns as New Spain, Louisiana, or the 13 Colonies would crash when they would be incorporated with their mother countries. This has been resolved with a small mod, but even then, their diplomacy's a bit messed; sometimes the option to establish alliances in diplomatic propositions is missing, as if they were still a protectorate even after declaring war on their mother countries. All the other minor factions are fine, though.
