There's been another couple of additions to the MPRPG Errata Page:
FORCE FIELD (p.38)
The rules as written do not offer the opportunity to re-distribute the Field's points of protection among different damage types. That is the best way to simulate a 'traditional' Force Field. However, GMs may choose to allow characters to re-distribute those points if it serves to better simulate a special, unique type of Force Field. We don't think it will break the game.
5.2 Environmental Effects (p.119)
Environmental damage counts as an 'area effect' vs. damage protection such as Armor (see 4.7.5.3), but shields have no effect against it.
