I mention running into a bug on 126.96.36.199 thread. That the creatures from previous version are not editable I manged to figure out what the actual cause is and what creatures, the bug is limited too. All creatures that had have adamantine DR (I am not sure why this one can't be changed), Alignment Based DR and Magic DR also, but those are no longer options in the newer version. Which would explain it. I took one of my creatures that had DR magic and another that had alignment from older version removed the dr. I then ported them over to 188.8.131.52 and they can now be edited. To test the admantine (since all my creatures with that dr are locked from kick-starter monster content) I removed the Dr in the old version, then upgraded it to 184.108.40.206. those creatures where editable after the fact.
