It doesn't really answer much of what I wanted them to address, and there is no errata (yet).

But it does settle the reroll-gate issue.

However, there are a couple other things that I noticed:

Supercharged plasma weapons will get hot 1/3 of the time when firing at venoms or mandrakes, because a roll of 2 will modify to a 1, and gets hot counts the post-modifier result.

You don't require line of sight to declare a charge, but you *do* need line of sight to fire overwatch. So, jump pack infantry that are hiding behind a nearby LOS-blocking piece of terrain can get an overwatch-free charge.

That might be a tactic to get Hellions into combat and infantry in general when moving through ruins.
