Other than winter increasing travel costs and decreasing gold income, are there any other seasonal effects?

Furthermore, does the Colossus move in a completely random fashion or does it's AI direct it towards enemies and sites of interest?

You mention in your battle with the cultist that "Then, the thick of battle swirled away for a moment and I got a clear view of my enemy, long enough to do something about putting a stop to his fell enchantments". Does this mean your spells can't target the back rows without the front rows being destroyed? Does this mean there has to be actual line-of-sight between your caster and the target? Or am I just reading too much into your choice of prose?
