Problem with adding a Mod...could use some help.

[Xedearnal]

So, I play FTB unleashed. I have modified the pack, I added a few mods and took a few mods out. So I don't think I should put this in the tech-support section. I'm adding CustomNPC's to the pack.

When I do, I get a crash because of block ID conflicts. So I switched the Block IDs from the default values to values I found that weren't used.

(I really don't understand exactly how this Mod is handling ID's, it give two places where ID's "start")

That fixed it so that it wouldn't crash when the game loaded, but for some reason its still trying to overwrite ID's that are in use by other mods. but I still get this when I try to load up a world:

This is bizarre because the ID's its trying to overwrite are nowhere near the ID's I told the mod in the configs to use. It set the two starting places to 1762 & 410, why is it overwriting ID's 2200 - 2238? Please help!

What that means is that you had an item with those ids, that no longer has them, or has been removed.

For example, you had "wrench" as 2238, but removed the mod that has "wrench"... just press yes, and then any items that no longer exist, will disappear, but if you replaced one of the old items' IDs, with the new items, then they will be replaced...

However, you are playing an old pack, so you may not find a lot of people willing to support it.

The above should work, but I would first make a backup just in case something didn't work.
