Convergence trap is not working, can not revoke the purge. Just sits in crafting que and does nothing.
You cannot summon a purge unless you are within the purge “time.” You can check your servers’ purge time in the server settings.
Welcome to the forums @Tyrorion 
Not trying to summon a purge, trying to revoke. To revoke which I have done before does not need a specific time. (Revoke, bring my purge meter down to zero.)
Is it turned on? Sometimes I stand there for a bit and then realize I accidentally turned off crafting on a work bench. I believe the convergence trap has a crafting switch as well iirc.
