Hey there. I fear that something very bad happened with
last Aquarium update. I just played Shellsmachine's tank and, where I would usually earn 400+ platinum (a score of 1000+), I only got 1. Or 0, not sure if that one was just the "navigation bonus" when I refreshed. TBH Shellsmachine's tank gave me the "you already played this game" error message under it, but I always received the correct amount of platinum even when getting that message, in the past. I don't know what's going on, but at this point Booty Grab could very well be dead to me since I get that error often enough and in some of the very best tanks.
(p.s. Before someone asks: no, I didn't reach the daily plat cap yet. Aside from some navigation, playing that tank was my very first action today.)
EDIT: I played your tank right now, and I got more than usual (300+ plat for a score around 200). It said you still got only 1 plat, sorry. I have no idea of why Shellsmachine's tank gave me none. If that's because of the "you already played this game" error, that sucks since of course I hadn't played that tank yet and I have no idea of why I get that error when I do, just that it happens often enough.
EDIT 2: I played another two tanks: Gravity is Just a Theory and Smartalaku2 (which is a full airsharks). At the end of both games, it said I earned only 1 (which was obviously wrong). The first one has given me the (I assume) correct amount of platinum--over 500-- but the second one gave me zero. I'm starting to think that the problem could be that now some scores are "too high" and the system is unable to calculate the correct platinum amount, giving 0 or 1 instead. I'm going to post all of this in the bugs forum, if no one has already.
