KNOWN ISSUE: Crash When Psyker's 'Mettle' Talent Reaches 31 Stacks (/extension_systems/buff/player_unit_buff_extension.lua:419: Cannot access property “template_name”)

FatsharkJulia · March 24, 2025, 4:24pm

A crash can occur when Psyker’s ‘Mettle’ Talent reaches 31 stacks of movement speed buff.

The error displayed will be similar to:

/extension_systems/buff/player_unit_buff_extension.lua:419: Cannot access property “template_name” on destroyed object of type Buff

This will be resolved in our upcoming hotfix, 1.7.1.

Thank you for your understanding and apologies for the inconvenience.

Any additional updates to this issue will be shared in the comments below and linked here.

Issue Type (Required):

Other

Issue Description (Required):

Every time I have attempted to play a mission thus far, the game crashes to desktop mid-mission within 5-10 minutes. The last 2 crashes were in the middle of playing the new Sefoni trial mode. This is on the PC Microsoft Store (Gamepass) version of the game.

The last 2 crash messages (only 1 attached, didn’t screencap the first one), labels the issue a [Script Error], seemingly to do with a player buff. This was from playing Sefoni’s new mode in the Nightmares & Visions update. Logs included.

I also crashed out within 5 minutes when attempting to just play a normal matchmaking mission.

Steps to Reproduce (Required):

Just playing any mission seems enough for me to run into a CTD. The frequency is high enough that I don’t intend to try and continue playing until some fixes go in.
