whats the reason to share compiled packs from teams?
i mean no offense but every team give you stable releases and only the developers can decide which rev is stable
basically not all npc have the lastfolk type only a few.You can use link packet for all NPC with lastfolk type if an NPC instance dont have the lastfolk you cant use link packeet with it thats when you need to add it.Its pretty easy 1 line only the NPC types are defined in gameserver.model.actor.instances package in java
easy to decide interlude is the most bugged client ever!just think about it 2years from custom shitty forks to fix il bugs and there are a lot of bug still!Gracia has a much more better support and because of that the bug correction is much more faster!
