[1.4.2][a48d] Engineer bonus for fort defenders doesnt work

[Nozovka]

Description: Bonus from engineers for fort defenders doesnt work (25% bonus to defence from engineers 1936). At the same time attackers recieve their 10% bonus from engineers (-35% penalty, not -45% when attacking lvl3 forts). Both divs at screenshots have engineers, province is protected by lvl3 fort
DLC's: no DLC
Mods: no mods active
Reproduction: It works always, the easiest way to check - attack Rhineland as Britain by 1 div with engineers in 1939 scenario

I've reported this bug here: https://forum.paradoxplaza.com/foru...-fort-river-defense-bonus-not-working.982794/

and got this answer from QA:

Yeah, this is weird one. I've gone ahead and entered this into our database. That said though, I would not expect a simple fix for the rivercrossing issue (which is currently curiously enough being applied as a reduction to the penalty to specifically breakthrough when attacking across a river). Since a division can be attacked from multiple directions it is fully possible to end up in a situation where only a subset of the attackers is affected by the rivercrossing. In this case the defense bonus makes little sense. It is not unlikely to get scrapped or changed when this eventually gets looked at (though I make no promises one way or the other).

I.e. if it ever gets fixed, the bonus will probably get removed entirely
