Obviously, I understand if you choose not to make this update, and I have no idea exactly how involved the changes are. But I thought that since you have such a useful mod for construction and design projects that using it with 4096 block IDs would be pretty killer.
Thank you so much for such a sweet mod and for all of your hard work.
Mods that need updating:
Animal Tamer Mod
GardenCraft - Modloader always complained about xy.png of the textures missing. Guess the Problem wasn't caused by 4096Blocks.
Unacceptable Kitchen - many Problems.
Millenaire - After assigning higher ID's: java.lang.NullPointerException at mod_Millenaire.<init> (mod_Millenaire.java:470)
GuiCraftory, Fishcraftory, Seasoncraftory, Runecraftory - Saving Chunks on World Creation and Load, can't see the reason right now.
Fancypack - Though this may be an error with Fancypack, and not an incompatibility.
Contron's NPC's - Patched by using MCPatcher, don't really know if it is because of MCPatcher or some incompatibility.
