Ok, so resPowers is defined in core thing_miscellaneous.dat file where it explains it as follows (in part):
Code:
<!-- Powers resource to track the number of arcane powers granted to the character -->
<thing
id="resPowers"
name="Arcane Powers"
compset="Resource"
panellink="arcane">
The only things I see on your dragon entry are for abBEExRaR, abBEPDra, and abBERadFi, so we might have to see those items to dig further. Nothing on the main dragonentry you have even references abBEPDra. If that AB is defined with 3 boostrapped powers, though, presumably you would need to cover the starting powers as 3 instead of the usual 1 with that.
Something is telling you the problem is in creBEDrag, though, right? Which means your error in the the first post isn't complete. Can you let us know what the error line is that mentioned creBEDrag?
