Mids' Hero/Villain Designer v1.900

One of the major reasons for DB breakage is the fact that Powersets and Powers are stored in arrays and their position in the array is used as the reference number to keep track of them. This "Static Index" is the thing that is recorded when you save a build or export or use Sentinel. If a power has an invalid Static Index or something happens to change a Static Index of an existing power/powerset, then the whole thing goes bonkers.

Up until 1.9, if you made a new power, the Static Index would be 0 until you saved, at which point it would get rewritten to the highest number. There was a bug with this, though, so in certain cases it would wind up with a lower number, causing a re-index of the list and the whole thing would break. In 1.9, I fixed it. I normally don't document fixes to the DB Editor, but there have been a few in 1.9 and 1.91.

Screwing up enhancements is part of this same thing, because Set Bonuses are actually powers, and they get stored in the same array. So while Multistrike might be saying "4th Set Bonus is Power #2342", the number 2342 might suddenly mean something completely different.

It's certainly more stable now than when that post was made (I believe Steiner worked on it, too, before he left), but it's still risky.
