Temple Thaumaturge's rooms dont drop medallions

Hello,

Just here to give you some facts :

This week i did like 20 temple, i have 8 thaumaturges rooms (lvl 1/2/3).

Its like 160 thaumaturges rooms killed and not a single medallions. Not a single one.

Tooltip say we are supposed to loot Quipolatl on tier 1 and 2 and advanced medallions on t3.

Am i extremly unlucky ? Tooltip is bugged ? or drop is bugged ?

Thx for reading
