Burrowing Bramble Bash - Timer not working for Party Member

Hello, THIS IS SUPER LOW PRIORITY but....


I partied with a friend and he came to my hideout to play Burrowing Bramble Bash.

He played solo while I stood outside.
Bramble Bash game started but he said timer did not go down (stayed at 45 seconds).

Bramble Bash game ends and gives him his score.

He tried it again, the game starts normally but the timer did not start again.

FYI, non-party members timer WORKS.

Timer not working appears to only affect party members
