It doesn't look like a specific variant, but an issue with the scripting for variants as a whole. If you select variants that replace bonus feats, only one of them seems to work properly. The additional ones only shift the bonus feat.

I noticed this when I was making the changeling egoist substitution levels. Two of the three (levels 1 and 5) replace bonus feats but instead of replacing both feats the changeling would still get one of them. At first I thought it was something I was doing but I tested it with the fighter variants and had the same result.

When modifying bonus feats through a class variant you have to modify the level where the change starts and *every* level thereafter. For example, the fighter class variant Resolve from Complete Champion replaces a fighter bonus feat at level 2. So, the array for this looks like this:

Ah, I see. In that case, Elusive Attack (PHB2) doesn't do that. It modifies the one level without modifying the rest.

A class variant allowing a whole category for bonus feats doesn't have them show up in the list for bonus feats.

Thanks. Fixed.

Looks like this works if you select specific feats but not feat groups. Not sure why, but I located one such example (Cleric trading Domains Bon Feat from Complete Champion) and fixed it with the following eval script:

Run at First / 10000
If you see other examples of this issue, please let me know.

Ok, I'm getting weird errors when using the Oracle template from Creatures of Rokugan. It says it is attempting to access an out of bounds matrix when calculating spells per day and spells known.

Hinder (Dragon Magazine) needs to have prereq adjusted. It gives an error if you don't have skirmish rather than checking if you do

The bonus mysteries for the shadowcaster (creator fix) only gives you the one stack of extra uses that can be used for any mystery for that level, not a bonus to each mystery

Fatespinner Class skills doesn't include Spellcraft (It should be included).
Practical Metamagic doesn't allow to select the Metamagic Feat of application.
Draconic Heritage doesn't qualify for the dragonblood requisite.

Unable to reproduce the error. It does look like there could be a problem with the secondary spells as it doesn't indicate how many the character receives. I'll look into this.

Thanks. Fixed.

Fixed

I'll look into this.

This one is a bit trickier as it's not necessarily a bug with the Draconic Heritage feat. Can you specify for which feat/PrC/whatever this isn't qualifyin for?

Dragon Wings, Practical Metamagic etc...
All the "Dragonblood Subtype required" feats from Dragon Magic and Races of Dragons
