P.S. Two implications of this: 1. The code you're looking at may not be the code that is executed. If in doubt, use the standard System Browser (not senders, implementers, etc.). 2. Iceberg may not be loading extension methods that override an existing method correctly, so the old version is left as the executable code. There may be happening in other situations as well, I haven't checked.
