Ritual Precursor Tablet drop rates are bugged for individual players.

There are many accounts across ingame and different platforms claiming that Ritual Precursor Tablet drop rates are extremely low or even 0 after the 0.3.1 patch.

I've asked ingame and on different platforms if anyone has a normal drop rate and got a yes everywhere.

For the people with low drop rates, I didn't find any similarities in atlas nodes, map juice, etc. If there is a bug, it seems to affect any level of investment.
