Changes Proposed

This fixes @fakename display. Currently it only displays if you have a disguise active.
Proposed changed = only shows when you don't have disguise active. Although, my personal opinion is there should be no check for disguise.

This one needs some clarification. Previously we did not check for sd->disguise in relation to fake names. Was there a report that said @fakename has some issues?

Yep works fine with disguise. I tried doing all sorts, like undisguising with fakename active, using fakename after activating disguise and so on.

I think the change from the original commit was done by mistake, the original commit clearly says

Send old name packet for players if fake name or disguise used

so i believe the fix shall be by replacing && with || and not just remove it.

The original commit that introduced the change: e68011e
