Help with ID's changing with map reload.[Solved]

[.Sullivan.]

Hello,

My server recently had to swap out maps and it appears that most of the ID's in 3 mods changed. There isn't a flexible ID option in any of those mods.

Anyone have a solution to prevent them from changing? And possibly setting them with a dedicated ID?

Cheers

Starting in 1.7, the level.dat file holds a set of mappings from each block/item name to an ID. As long as you copy the level.dat with the map, it should work fine, even between modpacks in many cases.

But if that gets messed up, you'll likely run into id problems.

That makes sense, thank you very much.
