Every time an LRM curves around a building, it's mostly by accident and not with any proper planning.
On top of that it doesn't account for the size of the building, or Radar Deprivation.
The "accident" is the missile tracking the target movement. Nothing much to do with the shooter or the target, that's the missile AI. Only the target can influence the missile movement, either by breaking lock or moving such that the LRMs Controlled Flight into Terrain (CFIT). In other words, crash into something else. The other variable is really the spotter, who feeds target lock back.
That's the fundamental. Everything else changes some variables in this, but the core remains.
Height of building just affects CFIT. If you dodge around a tall building and the missile tracks through the building, the missiles blow up against it. That happens often enough that it's a given. The complication really just comes in because the missiles exists in three dimensions, so it's a lot harder to gauge the path it might take, particularly since you're going to be a lot more busy dodging DF.
Radar Deprivation makes locks go away once you break LOS with all spotters, and that's the caveat -- all spotters. If even one still has LOS to you, the lock stays. So it's pretty useful in the initial contact phases of an engagement, and not as powerful once the enemy has either entered close range -- where locks are plentiful -- or when the enemy have infiltrated your lines and are spotting from behind your concealment.
On top of that, there's some greyness on how Radar Deprivation works against Advance Target Decay, but basic fundamentals are in place -- just some degrees of adjustments.
If I have one question to ask, what I'd ask is how does PGI program that AI tracking routine. Because seriously, sometimes the missiles just track too good, potentially doing collision avoidance on top of normal tracking. But again, from the air, a lot of maps are very exposed, so if a missile is merely tracking the path a mech is taking -- a mech which, naturally, cannot go through buildings -- it might be able to avoid buildings just merely by utilizing its height advantage.
Unfortunately, the tracking ability plus the trajectory behaviour information is just something PGI didn't release much on, as far as I know. There was an early thread about the trajectory change, but it was described in general, not specifics, which made it somewhat limited in use.
