Unifying Canada bug

[Artillery BOI]

whenever I play as one of the Canadian minors as soon as I begin confederating Canada Britain gets a Dominering attitude towards the player causing then to start a diplomatic play to annex you this is new to update 1.6 and a serious issue because it makes forming Canada nearly impossible

i've tested this on three different occasions every time the result is the same this is a reoccurring issue

I have seen parts of Australia being annexed in my games. Not even sure Britain AI annexing parts of India (puppets) is historical.

I wonder if it's just an issue when player does it?

In my america campaign, by about 1866 Hudson Bay Company had finished settling Alberta - was wanting to do a Canada play through too so was goona do a benchmark here to play later kind of thing.

For some reason HBC's presence across majority of Canada wasn't firing the status of a british minor fully controlling the provinces, so I basically kept switching between the minors of Columbia District / HBC / Upper Canada and giving states to upper canada, which was actually firing the status update that a minor was in control of the provinces.

When I'd given them the 9 required, I just switched back to USA and kept my game going, and canada confederated (New Brunswick was it's own minor too but was eventually absorbed via later event I assume).

I saved in 1866 again when the AI had confederated Canada for my later benchmark, but I wonder if letting AI do the confederation spared them the AI confusion of needing to reduce autonomy/annexing you? Canada seemed to be working the brief bit i checked it out by doing it this way at least, not sure if it'd actually work for you or if i just got lucky though.

edit: Could a distribution of power / etc law difference be causing the annexation?
