Steps: This is in regards to the Old World Fig x Royal Fern cross. The cross % on the Old World Fig (OWF) using G3 Thanalan soil appears to be around 45%. Testing numerous other crosses using OWF with G3 Thanalan shows the cross % around 90% (we've tested thousands of crosses to find this cross % with G3 Than).

We thought maybe ilvl of the seed was the reason for this so we decided to test OWF x Cloudsbreath (Royal Fern & Cloudsbreath ilvl are both 1). The cross % of the OWF next to Cloudsbreath is 90% debunking this theory as well.

Another theory we thought was maybe this specific cross (OWF x Royal Fern) was being reserved for a future alternate cross. However, every other cross that does not have an alternate cross doesn't behave this way (they all have 90% cross chance with G3 Than soil).

We cannot find any other reason for this low cross chance on the OWF when crossed with Royal Fern. We've confirmed over 4000 crosses and this seems to be the only one that behaves this way.
