"- undefidned defense" wehen decreasing defense


if I decrease enemy defense the message “- 106 undefined defense” in red text can be read for example.

Win 10 x64 | 0.10.0

What did I do?
I. e. decreasing enemy defense with Spew Acid or Crush Punch. The value seems to decrease correct only the red text has that “undefined” added.
If you use Devour you will see that the decreasing of other stats haven’t this addition.

Thank you again for looking into and best regards


I have used Devour on Thunder Salamander right now > Every stat had that “undefined” oO

Thanks, creating a fix for this now!
