Why does it say that I need 135P to generate an invite code?

It costs 135P now...

Its part of the new DYNAMIC invite point cost

It is because of the new Dynamic cost of invites that was implemented

EDIT: btw if you havent been active on forums, you might want to know about this point system update.....I recommend you to check the forums :P

Wow. That much for an invite? Sheesh. Well, thanks for answering. :)

Before it was 50P? What was wrong with that?

It is because many people invite (probably sell the invitations) people who do fake giveaways, give exploited keys, etc.. So if you invited somebody now, you gotta think about it good.

We also had double points before the change. Now is like paying quadruple the cost compared to the old system.
