Ok. This bug causes many debates in PureZC and forces many questmakers to learn Ghost.zh.
Remember NPC->Extend=3? This setting, theoretically, allows setting enemy size trough npc->Tilewidth and npc->Tileheight. The problem, though, is the fact that all frames of animation (including all directions) must fit in one row of tiles (20 tiles). Otherwise the enemy uses seemingly random tiles in tile sheet with no pattern to figure out. If animation option includes additional frames (like Firing) those frames will also be random and glitchy.

Any way to fix this? As Ghost.zh can slow down ZC on old machines.
