Referral's globals

Each player can have four types of globals, i.e. platinum, gold, crystals, item.

At the moment only 50% of those types work for the 5% referral bonus, that is platinum and gold. I cannot find a way for "item" global drop to somehow have a benefit to the referrer (could be a small amount of gold or something).

The big issue I spot here is the "crystal" global. After two months or so of gameplay I only got a maximum of 7 crystals from global boost. At 5% this translates to a mere 0,35 of crystal. I believe noone got over 20(!) crystals in a global drop, so that it could translate to 1 crystal at 5% bonus and if that happens it will probably be after 8-12 months.

So, I see two solutions to correcting this issue.

a) round every crystal global drop to 1 . (easy fix!)

or

b) like fame works (i.e. you gained 1.2 fame) have them combine, so everytime a referrals' crystal globals add to be 20, 1 crystal will be attributed to the referrer.

Oh and please make the bug fix retroactive.

Thanks!
