How does East invaded works?

Hi, i have a question on how the EI event is implemented, or if i missed a rule (again).

I have a game where as the Axis, i prepared to USSR invasion by massing troops at the border, while my oponant keeps their units a little further.
Displacing a unit (from Bessarabia to Poland) by clicking directly to its final destination, i saw (quite horrified) the unit taking a shortcut within USSR territory.
I canceled the move, re-did my movement taking a safe way. No conditional event seems to have been triggered so far.

From rule 13.3, East Invaded occurs when “an Axis unit […] moves into […] USSR”.
The way i understand this makes me believe i made a huge mistake.
Shall my move have been a “not-cancelable” one?
What would have happened if i did not cancel it?

I don’t know if i am misinterpreting the rules, or if i deceived the game implementation

Could you give your table number please (you're playing several games).

Look at the log after your move - it will have a bold message telling you East Invaded if you triggered the event.

The table number is:
262066907
and the game move was maybe 1613 (how can i be sure?)
It was with ROM3 moving in 2939 then 2837, starting from 3242 i believe.
It is clearly writthen in the log i canceled my initial move.
The game continued and there was no East Invaded (nor in the log).

So the cancel button seems quite strong.
But we agree that passing through (without stopping in) USSR should trigger EI?

Since unit routes are decided by the route-finding mechanic and that occasionally makes errors I think it is best Undo would be usable on them. Activating East First too early can be bad enough to warrant resigning between relatively equal players.
