My friend's server receives this error when trying to boot up with dramatic doors.

@Inject(@at("INVOKE")) Shift.BY=2 on dramaticdoors.micins.json:OpenDoorsTaskMixin from mod dramaticdoors: :handler$bhm000$injectStartP1 exceeds the maxium allowed value: 0. Increase the value of maxShiftBy to suppress this warning

I should look into it. It doesn't crash the server, does it?

Turns out it wasn't anything mod related, it was on their side, apologies for this.
