Vigour catalyst 2 is STILL broken according to its description

[vdragon]

Is it similar to this?

Draining boon combound debuff

When forging, if you use vigour catalyst straight after corrupted boon combound then the debuff is never applied. With draining boon combound the debuff is applied once even though vigour catalyst gives bonus for all 3 rounds. Is this intended or a bug?
