I had a strange issue. I was donating ( and testing the donation limit thingie ) something like 20+ gassifiers. I used a Grendaline shrine and it warned me of going over the limit. I said ok and it got me some points and a some XP. I did tried again after that and i got something like 4320 xp for a 6000 currants donation ( a lot of gassifiers ) and no points. Which is fine. But after that i tried the same thing with Mab. Now if i donate something like a gassifier to Mab i get nothing ( no XP and no Shrine points ). But if i donate meat or something else i get xp :)
I don't know if it's a bug or how it's supposed to work but i think it's a bug because i would expect some message telling me that the donation would be useless :)
