While playing through the Firewatch Fighter's Guild questline on the most recent TR_Mainland version, I was not able to progress the quest Find Mashug gro-Dugal. I talked to Mashug and he mentions the trap as you step onto the carpet, but this does not occur for me. Standing on the platform he stands on before talking to him does not seem to fix the issue. I am not able to trigger the trap he mentions in any way.

Looking at the way the quest is set up, it seems the script that is fired does not work. He does not move from his platform as he should. I am uncertain if the script is firing at all.
