Ablative Carapace is trying to stack instead of refresh

[dzyp]

Running as a wm/bio scrapper, if I activate ablative carapace my absorption points will jump up to 1191, which is expected. However, if I don't wait for that to expire and hit ablative carapace again, instead of refreshing it stacks so when the previous cast expires the new absorption points is ~100 (ie, carapace stacked, I hit the absorption cap, then the first cast expired so my new absorption points is the difference between my cap and 1191).

Note that this doesn't happen every time, I'd say somewhere between 25-50%. Could be a race condition.

CoD says this should refresh: https://cod.uberguy.net/html/power.html?power=scrapper_defense.bio_organic_armor.ablative_carapace&at=scrapper
