[BUG] Disciple Oasis crashes game when converting Chilled Ground (since previous patch)

This crash has been happening since the previous patch and is still present after the latest patch, but I don’t see it mentioned as fixed.

I’m playing a Disciple and getting extremely frequent crashes (unexpected disconnects). Around 9 out of 10 maps crash, causing full loss of map progress, rewards, and Waystones. This also affects Logbooks and Trial of Chaos.

Repro steps (consistent):

Use Nova to create Chilled Ground

Use the Disciple Oasis skill (converts Chilled Ground into Oasis)

Game crashes immediately when Oasis is created

This is not a hardware or client-only issue:

I tested this with party members (1+ players) and everyone crashes together

I also went to a friend’s Hideout, used the skill interaction, and the game crashed there as well

The issue started last patch and is not addressed in the current patch notes.
This looks like a bugged interaction with Chilled Ground → Oasis conversion and makes the character basically unplayable.
