Describe the bug
From Discord:

hi!! sorry if this has been asked before, but im having an issue with mountain shrines. So with 2 people and 1 shrine, we want 4 items to drop, but its only dropping 3 items. I've tried turning Override boss loot scaling off but it doesn't seem to be affecting it, is there anything I can do to make it work the vanilla way?
wait shouldn't it be dropping 2 items?
Well, I tried changing the boss loot credit number from 1 to 2 initially in hopes that it would register the mountain shrine multiplier as 2 players, but it seemed to just do it for the initial drop, then counting the mountain shrine as 1 player still
yeah so this suggests its boss loot credit + amount of mountain shrines

To Reproduce
Steps to reproduce the behavior:

1. Activate shrines of the mountain with more than one player
2. Start teleporter
3. Count amount of items.

Expected behavior
See above
