Rng?

Spy sometimes unable to attack the building. Horse sometimes moves one square only even on neutral territory regardless of the roads or mountain starting point. Horse bouncing off distance also seems random.

I remember blaming rng when some ruins were inaccessible before discovering that some of them are on the mountains so climbing needs to be unlocked first or how roads affect the movement so I am no longer jumping to conclusions. I play live timer games only and haven't studied the game mechanics that much in sp so I might be missing more patterns.
