dunno if this is a bug, but we were able to pass through this, was looking for a way to get rid of the orange corruption! it's not able to be cleaned.
Passing through is a bug, thank you for reporting this. It will be fixed in an update we're working on right now ^^
The orange corruption will go away once you've cleaned the full stone pillar, it can be a bit tricky to find all the corruption on the pillar. We're currently investigating ways to make it easier to find those last nasty corruption bits 🔎
We have noticed through some gameplay videos, that when using the aim/power washer to clean, some clusters on the stone pillar look completely clean except for some hidden pixels.
We hope to release an update soon that addresses this issue. In the meantime, spraying the clusters without foliage, without aiming, seems to hit those pixels much easier.
