Andreas J. said: It has likely something to do with how the sheetworkers are made to calculate some stats differently for PC/NPC. Sure sounds like a few core cases like AC/speed could be nice to be consolidated into working off the same attribute, but have no idea how those parts of the sheet work. I've brought up this topic with the others on my team. This is very likely the problem: the stats are calculated differently. But it's a problem that could easily be solved by the designer. They could have the sheetworker that calculated npc stats only trigger when the sheet type flag is set to npc, and the pc ones trigger when it's set to pc. Then you can use the same final ac and speed stat for both, even if the foundational attributes are different. Edit: even easier, calculate things exactly the same, and just have, say, AC, which is just set by the sheet type attribute, getting the appropriate final stat from either pc or npc stat as appropriate. Such a thing really should be implemented, since it makes it easier for players and GMs setting up macros, You dont have to examine the sheet to figure out what the relevant stats are called, and use different macros for each. As it is you cant use a targetting macro, because the AC stat is different depending on who you are targeting, and that's a problem.
