Possible solution to the sap death bug

1) to be sure, did you just apply Bropedio's Function C2/4BF4 changes from the 1st post, or also his Function C2/4C5B changes from the 2nd post?  the latter does restrict usage of non- FC 12/FC 1C counters in a small amount of cases.

2) do you have Leet Sketcher's Item/Magic Counter bugfix applied?  it's a later sibling of Master ZED's FC 05, so could present issues, based on how i responded to Pandora's Box using that approach in the old Mnrogar forum thread.
