When using the BetterVanillaBuilding Resource Pack (download here), most everything seems to be working as intended (at least from what I can see), except for chests. Chests are invisible, but when you open them you are able to see the top of the chest.

When applying the pack I'm getting the broken path message (I have broken paths enabled in the config). How can I fix this or direct the resource pack author to fix it?

Here is my latest.log

Have you tried removing CIT Resewn to make sure that this is the mod that causes it? there is nothing that would mess with the chest model in CIT Resewn and you seem to have a lot of other mods doing a lot of things with resourcepacks.

To make things easier, Fabulously Optimized is the base modpack I'm using.

Yeah I tried disabling a number of the other mods that I thought would be the culprit and the chest only appeared once I disabled CIT Resewn.

Yeah, sorry but I cannot reproduce this :/
I tried on a clean set up and using the modpack and the chests always appear properly.

As I said, there should not be anything that messes with chests in CIT Resewn.

I'll reopen the issue if you manage to narrow down the circumstances further or if someone else can reproduce this.

To narrow it down you could:

• Try getting rid of other mods to see if only when cit resewn is present with another mod is the cause.
• Try deleting files in the resourcepack until it works.
• Try playing with different settings you have in other mods.
