how many ticks does the havoc last

please tell

That is up to the admin, there is no set number but it will be based on other factors such as how many worlds have recently reset.

Usually they will last around 2 to 3 days after the last era reset on the queue

So if m2 goes into havoc first before m3, then m3 havoc will end around 2 to 3 days after m2 reset.

Ofc this is not 100% true, but at least this is the usual stuff
