Crashing in Public Worlds - NullReferenceException

[Gamersven]

Hi,
me and my friends were crashing frequently and i started to investigate the cause.
we found that function AdvancedInvites.Utilities.AllowedToInvite() was crashing us.

After some investigation i found that the OwnerId is null in Public Instances and was causing a System.NullReferenceException.

I fixed it up that i checked if the OwnerId is not null and then proceded.

My Code it kinda trash, so i didint PR it.

Greetings from Germany and thanks for your work!

? is pretty much checking for null. there's also ?? to check if left is null. if it is then right and some others. newer c# like ??= is if this variable is null, then assign this.

name ??= "something";

there's a lot with these questionmarks to do in c# and so far the code you showed isn't really bad. there's also exclamationmark ! in c# whihci is null supressor. basically ignoring that it might be null and telling it won't be
