I'm afraid I'm confused about what the problem is then... @ZoriaRPG can you elaborate?

In any case, Zoria, the TL;DR of this thread is that any change must

1. preserve backward-compatibility of 2.50.x with respect to quests saved in old versions of ZQ;
2. preserve backward-compatibility of master with respect to 2.50.x (from the perspective of master, 2.50.x *is* an "old version" even though it's not released yet!)

These are "iron laws" in the sense that a change that breaks one is almost always a bad change, regardless of its other merits. I rolled back the NEWCOMBOSDM rule because it ran afoul of (2).
