Game is crashing on server startup, tried both an existing 1.12.2 world as well as a brand new 1.12.2 world, both crash on startup... existing world was created as a new 1.12.2 world about 2 weeks ago. No other mods running.

Buildcraft Version 7.99.12 (buildcraft-core-7.99.12.jar)
Forge Version 2555 (forge-1.12.2-14.23.1.2555-universal.jar)

Duplicate of #3873 and #3858.

@Remanent it should work with the modules from https://www.mod-buildcraft.com/releases/testing/BuildCraft/7.99.13-prereleases/modules/ (which is basically stable, just not released yet.)

the problem is you installed only the core module of buildcraft and that has an dependency on the builders module it shoudn't have (see #3858 )

though since you only have the core module i think you probably ment to install the full version and grabbed the wrong file instead

I was trying to use the transport pipes as well, but it cept crashing on startup.. i don't want all of the mod

can you add builders and transport then and if it still crashes give a new crash report?

Copy, working on it now. Will be back in a few, using the released versions i assume.

No crash using Core, Transport, and Builders during server startup...

alright probably was the same crash then, once 7.99.13 is out you should be able to remove builders again if you want

Getting a client crash during client startup using the core, builders, and transport pipes on the client side.

Buildcraft Version 7.99.12 (buildcraft-core-7.99.12.jar, buildcraft-builders-7.99.12, buildcraft-transport-7.99.12)
Forge Version 2555 (forge-1.12.2-14.23.1.2555-universal.jar)

seems there still are some issues with separation of things into the modules

Do you want me to start a new issue for this since this is technically closed?

sorry ment to click 're-open and comment' earlier

@AlexIIL Thank You.

Was playing with it, and it's loaded w/ just core and transport without crashes, the guide book however only shows the recipes in game for the core mod, and nothing from the transport mod (looking to introduce this mod to some players that haven't seen it before, and was going to give each of them the book to use since it's there).

The guide is still a WIP unfortunately. Although you can view recipes from other sections by clicking on crafting components (as it takes you to a new page with all of the crafting recipes involving that resource), its just a little annoying as there's no search feature yet, and you have to click through lots of pages and items in order to get to the recipe that you want.

@AlexIIL Ah, gotcha. Definitely not intuitive, but it does work. Thanks again.
