Ladder questions

Hello

1- if player does not do anything after getting challenged, system gives the win (walkover) to the challenger after how long (time limit)?

2- If the system gives the walkover win (time ran out without accepting/declining), does it count as a victory for the challenger and gets added to his stats? or he just goes over his opponent in the ladder standings without scoring a victory?

3- same question as #2 but for the person who got challenged and did not react in time, does he get a defeat added to his stats or not?

I have not run any update yet (Arcane and tournament plugin) in case it’s different in the new version for the above questions.

Thanks
